Xiaomi Redmi Note 8 64Gb+6Gb Dual LTE [86/132] Gyroscope

through the android.hardware.location.gps feature flag and the LocationManager.getGnssYearOfHardware() Test

API reports the year "2016" or newer, they:

[C-2-1] MUST report GNSS measurements, as soon as they are found, even if a location

calculated from GPS/GNSS is not yet reported.

[C-2-2] MUST report GNSS pseudoranges and pseudorange rates, that, in open-sky

conditions after determining the location, while stationary or moving with less than 0.2

meter per second squared of acceleration, are sufficient to calculate position within 20

meters, and speed within 0.2 meters per second, at least 95% of the time.

If device implementations include a GPS/GNSS receiver and report the capability to applications

through the android.hardware.location.gps feature flag and the LocationManager.getGnssYearOfHardware() Test

API reports the year "2017" or newer, they:

[C-3-1] MUST continue to deliver normal GPS/GNSS location outputs during an emergency

phone call.

[C-3-2] MUST report GNSS measurements from all constellations tracked (as reported in

GnssStatus messages), with the exception of SBAS.

[C-3-3] MUST report AGC, and Frequency of GNSS measurement.

[C-3-4] MUST report all accuracy estimates (including Bearing, Speed, and Vertical) as

part of each GPS/GNSS location.

If device implementations include a GPS/GNSS receiver and report the capability to applications

through the android.hardware.location.gps feature flag and the LocationManager.getGnssYearOfHardware() Test

API reports the year "2018" or newer, they:

[C-4-1] MUST continue to deliver normal GPS/GNSS outputs to applications during a

Mobile Station Based (MS-Based) Network Initiated emergency session call.

[C-4-2] MUST report positions and measurements to the GNSS Location Provider APIs.

7.3.4. Gyroscope

Device implementations:

SHOULD include a gyroscope (angular change sensor).

SHOULD NOT include a gyroscope sensor unless a 3-axis accelerometer is also included.

If device implementations include a gyroscope, they:

[C-1-1] MUST be able to report events up to a frequency of at least 50 Hz.

[C-1-2] MUST implement the TYPE_GYROSCOPE sensor and SHOULD also implement

TYPE_GYROSCOPE_UNCALIBRATED sensor.

[C-1-3] MUST be capable of measuring orientation changes up to 1,000 degrees per

second.

[C-1-4] MUST have a resolution of 12-bits or more and SHOULD have a resolution of 16-

bits or more.

[C-1-5] MUST be temperature compensated.

[C-1-6] MUST be calibrated and compensated while in use, and preserve the

compensation parameters between device reboots.

[C-1-7] MUST have a variance no greater than 1e-7 rad^2 / s^2 per Hz (variance per Hz, or

rad^2 / s). The variance is allowed to vary with the sampling rate, but MUST be

constrained by this value. In other words, if you measure the variance of the gyro at 1 Hz

sampling rate it SHOULD be no greater than 1e-7 rad^2/s^2.
