GPY - Compact format for GNSS data

GNSS Frames - 0xE0 and 0xD0

This format is generated by the ESP GPS and derivatives.

The majority of the data originates from UBX-NAV-PVT (navigation solution - position / velocity / time).

GPY Name Raw Name Type Name Type Units Resolution
Horizontal DOP 1 2 hdop <u2 hdop float32 - 1 x 10-2
UTC Time utc <u8 ts float64 s 1 x 10-3
Speed speed <u4 sog float32 m/s 1 x 10-3
Speed Error speed_err <u4 ehve float32 m/s 1 x 10-3
Latitude latitude <i4 lat float64 deg 1 x 10-7
Longitude longitude <i4 lon float64 deg 1 x 10-7
Course course <u4 cog float32 deg 1 x 10-3
Satellites satellites u1 sat uint8 - -
Fix fix u1 fix uint8 - -

Notes:

  1. Horizontal dilution of precision (HDOP) originates from the NAV-DOP message.
