124 Copernicus GPS Receiver
Timing Packets
If you are using the Lassen IQ GPS Receiver as a timing reference, you may need to
implement the following TSIP control commands.
Table A.5 Timing Packets
Satellite Data Packets
The following packets contain a variety of GPS satellite data.

Backwards Compatibility to Lassen iQ
The following General Packets and Differences between TSIP Used in Lassen iQ/SQ
and Copernicus GPS Receiver
• 0x41, 0x46, 0x4B automatic packets are output every 1 second instead of every
5 seconds.
• DGPS is not supported in the Copernicus GPS Receiver. Thus, the following
packets are not supported:
0x60 /0x61
0x65/0x85
• 0x69 / 0x89 not available. The Lassen IQ GPS Receiver is a high sensitivity
receiver.
• 0x70 packet is not supported in the Copernicus GPS Receiver. The Copernicus
GPS Receiver supports only Kalman Filter and it can not be turned off. No PV
filter is available in Copernicus Module.
• Packet 0xC0 – Graceful Shutdown and Go To Standby Mode is supported in
the Copernicus GPS Receiver.
• In “Key Setup Parameters of Packet BB”, BB packet is still the same, but:
Cannot set signal mask.
Fix mode/DOP mask/DOP switch/DGPS correction age are not supported.
