0x59 Report Packet 59

Satellite Attributes Database Report

This packet is returned in response to packet 39 if operation mode 3 or 6 is used with packet 39.

Normally the GPS receiver selects only healthy satellites (based on transmitted values in the ephemeris and almanac) which satisfy all mask values, for use in the position solution.

Packet 59 indicates whether each satellite is allowed or not allowed to be selected for use in the position solution, or whether each satellite’s health is to be heeded or ignored. The data format is shown below.

!Note – When viewing the satellite disabled list, the satellites are not numbered but are in numerical order. The disabled satellites are signified by a 1 and enabled satellites are signified by a 0.
