## Constants
### ADR_STATE_CYCLE_SLIP
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static val ADR_STATE_CYCLE_SLIP: Int
```
The state of the `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` has a cycle slip detected.
Value: 4
### ADR_STATE_HALF_CYCLE_REPORTED
Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static val ADR_STATE_HALF_CYCLE_REPORTED: Int
```
Reports whether the flag `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_HALF_CYCLE_RESOLVED:kotlin.Int` has been reported by the GNSS hardware.
When this bit is set, the value of `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeUncertaintyMeters()` can be low (centimeter level) whether or not the half cycle ambiguity is resolved.
When this bit is unset, the value of `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeUncertaintyMeters()` is larger, to cover the potential error due to half cycle ambiguity being unresolved.
Value: 16
### ADR_STATE_HALF_CYCLE_RESOLVED
Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static val ADR_STATE_HALF_CYCLE_RESOLVED: Int
```
Reports whether the value `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` has resolved the half cycle ambiguity.
When this bit is set, the `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` corresponds to the carrier phase measurement plus an accumulated integer number of carrier full cycles.
When this bit is unset, the `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` corresponds to the carrier phase measurement plus an accumulated integer number of carrier half cycles.
For signals that have databits, the carrier phase tracking loops typically use a costas loop discriminator. This type of tracking loop introduces a half-cycle ambiguity that is resolved by searching through the received data for known patterns of databits (e.g. GPS uses the TLM word) which then determines the polarity of the incoming data and resolves the half-cycle ambiguity.
Before the half-cycle ambiguity has been resolved it is possible that the ADR_STATE_VALID flag is set:
- In cases where ADR_STATE_HALF_CYCLE_REPORTED is not set, the ADR_STATE_HALF_CYCLE_RESOLVED flag will not be available. Here, a half wave length will be added to the returned accumulated delta range uncertainty to indicate the half cycle ambiguity.
- In cases where ADR_STATE_HALF_CYCLE_REPORTED is set, half cycle ambiguity will be indicated via both the ADR_STATE_HALF_CYCLE_RESOLVED flag and as well a half wave length added to the returned accumulated delta range uncertainty.
Value: 8

## Public methods
### describeContents
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun describeContents(): Int
```
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.Int)`, the return value of this method must include the `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int` bit.
| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int` |
### getAccumulatedDeltaRangeMeters
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun getAccumulatedDeltaRangeMeters(): Double
```
Gets the accumulated delta range since the last channel reset, in meters.
The error estimate for this value is `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeUncertaintyMeters()`.
The availability of the value is represented by `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeState()`.
A positive value indicates that the SV is moving away from the receiver. The sign of `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` and its relation to the sign of `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getCarrierPhase()` is given by the equation:
```kotlin
accumulated delta range = -k * carrier phase (where k is a constant)
```
Similar to the concept of an RTCM "Phaserange", when the accumulated delta range is initially chosen, and whenever it is reset, it will retain the integer nature of the relative carrier phase offset between satellites observed by this receiver, such that the double difference of this value between receivers and satellites may be used, together with integer ambiguity resolution, to determine highly precise relative location between receivers.
The alignment of the phase measurement will not be adjusted by the receiver so the in-phase and quadrature phase components will have a quarter cycle offset as they do when transmitted from the satellites. If the measurement is from a combination of the in-phase and quadrature phase components, then the alignment of the phase measurement will be aligned to the in-phase component.
### getAccumulatedDeltaRangeState
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun getAccumulatedDeltaRangeState(): Int
```
Gets 'Accumulated Delta Range' state.
This indicates the state of the `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getAccumulatedDeltaRangeMeters()` measurement. See the table below for a detailed interpretation of each state.
| ADR_STATE | Time of relevance | Interpretation |
|---|---|---|
| UNKNOWN | ADR(t) | No valid carrier phase information is available at time t. |
| VALID | ADR(t) | Valid carrier phase information is available at time t. This indicates that this measurement can be used as a reference for future measurements. However, to compare it to previous measurements to compute delta range, other bits should be checked. Specifically, it can be used for delta range computation if it is valid and has no reset or cycle slip at this epoch i.e. if VALID_BIT == 1 \&\& CYCLE_SLIP_BIT == 0 \&\& RESET_BIT == 0. |
| RESET | ADR(t) - ADR(t-1) | Carrier phase accumulation has been restarted between current time t and previous time t-1. This indicates that this measurement can be used as a reference for future measurements, but it should not be compared to previous measurements to compute delta range. |
| CYCLE_SLIP | ADR(t) - ADR(t-1) | Cycle slip(s) have been detected between the current time t and previous time t-1. This indicates that this measurement can be used as a reference for future measurements. Clients can use a measurement with a cycle slip to compute delta range against previous measurements at their own risk. |
| HALF_CYCLE_RESOLVED | ADR(t) | Half cycle ambiguity is resolved at time t. |
| HALF_CYCLE_REPORTED | ADR(t) | Half cycle ambiguity is reported at time t. |
| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | Value is either `0` or a combination of the following: - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_UNKNOWN:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_VALID:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_RESET:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_CYCLE_SLIP:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_HALF_CYCLE_RESOLVED:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#ADR_STATE_HALF_CYCLE_REPORTED:kotlin.Int` |
### getAccumulatedDeltaRangeUncertaintyMeters
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

### getAutomaticGainControlLevelDb
Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
Deprecated in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun getAutomaticGainControlLevelDb(): Double
```
**Deprecated:** *Use `https://developer.android.com/reference/kotlin/android/location/GnssMeasurementsEvent#getGnssAutomaticGainControls()` instead.*
Gets the Automatic Gain Control level in dB.
AGC acts as a variable gain amplifier adjusting the power of the incoming signal. The AGC level may be used to indicate potential interference. Higher gain (and/or lower input power) shall be output as a positive number. Hence in cases of strong jamming, in the band of this signal, this value will go more negative. This value must be consistent given the same level of the incoming signal power.
Note: Different hardware designs (e.g. antenna, pre-amplification, or other RF HW components) may also affect the typical output of of this value on any given hardware design in an open sky test - the important aspect of this output is that changes in this value are indicative of changes on input signal power in the frequency band for this measurement.
This field is part of the GnssMeasurement object so it is only reported when the GNSS measurement is reported. E.g., when a GNSS signal is too weak to be acquired, the AGC value is not reported.
The value is only available if `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#hasAutomaticGainControlLevelDb()` is `true`
### getBasebandCn0DbHz
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
Gets the baseband carrier-to-noise density in dB-Hz.
Typical range: 10-50 dB-Hz. The range of possible baseband C/N0 values is 0-63 dB-Hz to handle some edge cases.
The value contains the measured C/N0 for the signal at the baseband. This is typically a few dB weaker than the value estimated for C/N0 at the antenna port, which is reported in `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getCn0DbHz()`.
| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-double/index.html` | Value is between 0.0f and 63.0f inclusive |

```
fun getReceivedSvTimeNanos(): Long
```
Gets the received GNSS satellite time, at the measurement time, in nanoseconds.
The received satellite time is relative to the beginning of the system week for all constellations except for Glonass where it is relative to the beginning of the Glonass system day.
The table below indicates the valid range of the received GNSS satellite time. These ranges depend on the constellation and code being tracked and the state of the tracking algorithms given by the `https://developer.android.com/reference/kotlin/android/location/GnssMeasurement#getState()` method. The minimum value of this field is zero. The maximum value of this field is determined by looking across all of the state flags that are set, for the given constellation and code type, and finding the the maximum value in this table.
For example, for GPS L1 C/A, if STATE_TOW_KNOWN is set, this field can be any value from 0 to 1 week (in nanoseconds), and for GAL E1B code, if only STATE_GAL_E1BC_CODE_LOCK is set, then this field can be any value from 0 to 4 milliseconds (in nanoseconds.)

Note well: if there is any ambiguity in integer millisecond, STATE_MSEC_AMBIGUOUS must be set accordingly, in the 'state' field. This value must be populated, unless the 'state' == STATE_UNKNOWN.
Note on optional flags:
- For L1 C/A and B1I, STATE_SYMBOL_SYNC is optional since the symbol length is the same as the bit length.
- For L5Q and E5aQ, STATE_BIT_SYNC and STATE_SYMBOL_SYNC are optional since they are implied by STATE_CODE_LOCK.
- STATE_2ND_CODE_LOCK for L5I is optional since it is implied by STATE_SYMBOL_SYNC.
- STATE_2ND_CODE_LOCK for E1C is optional since it is implied by STATE_GAL_E1C_2ND_CODE_LOCK.
- For E1B and E1C, STATE_SYMBOL_SYNC is optional, because it is implied by STATE_GAL_E1BC_CODE_LOCK.
