33 HID Sensor Usages
Unit Exponent.
Altitude Sealevel SV – Indicates altitude referenced to sea level. Default unit of
measure is meters; can be overridden using explicit Unit and/or
Unit Exponent.
DPGS Data Age SV – Indicates age of differential GPS data. Default unit of
measure is seconds; can be overridden using explicit Unit and/or
Unit Exponent.
Error Radius SV – Indicates accuracy of latitude and longitude values. Default
unit of measure is meters; can be overridden using explicit Unit
and/or Unit Exponent. A value of 0 means that the accuracy level
is not currently known.
Fix Quality NAry – Indicates fix quality:
Sel – No Fix,
Sel – GPS,
Sel – DPGS.
Fix Type NAry – Indicates fix type:
Sel – No Fix,
Sel – GPS SPS Mode, Fix Valid,
Sel – DGPS SPS Mode, Fix Valid,
Sel – GPS PPS Mode, Fix Valid,
Sel – Real Time Kinematic,
Sel – Float RTK,
Sel – Estimated (dead reckoned),
Sel – Manual Input Mode,
Sel – Simulator Mode.
Geoidal Separation SV – Indicates the difference between the World Geodetic System
(WGS 84) ellipsoid and mean sea level. Values less than zero
indicate that mean sea level is below the reference ellipsoid.
Default unit of measure is meters; can be overridden using explicit
Unit and/or Unit Exponent.
GPS Operation Mode NAry – Indicates GPS operation mode:
Sel – Manual = Manually set for 2D or 3D mode ,
Sel – Automatic = Automatically can switch between 2D and
3D modes.
GPS Selection Mode NAry – Indicates GPS selection mode:
Sel – Autonomous,
Sel – DGPS,
Sel – Estimated (dead reckoned),
Sel – Manual Input,
Sel – Simulator,
Sel – Data Not Valid.
GPS Status NAry – Indicates current GPS data status:
Sel – Data Valid,
