TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP)<br />

Byte Offset Item Type Value Definition<br />

38+N*4<br />

Measurement<br />

Status<br />

UINT8 Bit-masks Bit 2 - if set, time ambiguity<br />

is resolved (channel is<br />

acquired).<br />

Bit 4 - if set, ephemeris is<br />

decoded.<br />

Other bits are reserved.<br />

39+N*4<br />

Fix Mode / Rejection<br />

Code<br />

UINT8 Any 0x00 - SV is used in<br />

computing the current<br />

position fix.<br />

0x01…0xFF - SV is not used<br />

in fix. The value indicates<br />

the internal “rejection”<br />

code.<br />

Note – To convert to radians, multiply the received latitude or longitude value by<br />

(PI/2 31 ). For longitude, if the converted value is greater than PI, subtract 2*PI (PI =<br />

3.1415926535898) to bring the final value to the (-PI…+PI) range.<br />

The channel tracking block (4 bytes in length) is repeated for all 12 channels.<br />

Report Packet 0x8F-4F - Set PPS Width<br />

Note – This report packet is output after the command packet 0x8E-4E has been<br />

executed. See the corresponding command packet for information about the data<br />
