TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP)<br />

Timing Packets<br />

If you are using the Lassen IQ GPS Receiver as a timing reference, you may need to<br />

implement the following TSIP control commands.<br />

Table A.5<br />

Timing Packets<br />

Input ID Description Output ID<br />

0x21 get the current GPS time 0x41<br />

0x38-05 request UTC parameters 0x58-05<br />

Satellite Data Packets<br />

The following packets contain a variety of GPS satellite data.<br />

Table A.6<br />

Satellite Data Packets<br />

Input ID Description Output ID<br />

0x27 request signal levels 0x47<br />

0x38 request/load satellite system data 0x58<br />

0x3C request tracking status 0x5C<br />

Backwards Compatibility to Lassen iQ<br />

The following General Packets and Differences between TSIP Used in Lassen iQ/SQ<br />

and Copernicus GPS Receiver<br />

• 0x41, 0x46, 0x4B automatic packets are output every 1 second instead of every<br />

5 seconds.<br />

• DGPS is not supported in the Copernicus GPS Receiver. Thus, the following<br />

packets are not supported:<br />

0x60 /0x61<br />

0x65/0x85<br />

• 0x69 / 0x89 not available. The Lassen IQ GPS Receiver is a high sensitivity<br />

receiver.<br />

• 0x70 packet is not supported in the Copernicus GPS Receiver. The Copernicus<br />

GPS Receiver supports only Kalman Filter and it can not be turned off. No PV<br />

filter is available in Copernicus Module.<br />

• Packet 0xC0 – Graceful Shutdown and Go To Standby Mode is supported in<br />

the Copernicus GPS Receiver.<br />

• In “Key Setup Parameters of Packet BB”, BB packet is still the same, but:<br />

Cannot set signal mask.<br />

Fix mode/DOP mask/DOP switch/DGPS correction age are not supported.<br />
