Copernicus GPS Receiver 1 7 5

TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP) A

Note – This value is valid only if Bit 7 of the Receiver Health byte is not set. To
compute the complete GPS time of measurement to 1 ns resolution, use the following
formula:
GPS Time of Measurement (nanosec) = GPS Millisec*1000000 + Fractional GPS
Nanosec

Note – The channel tracking block (12 bytes in length) is repeated for all 12 channels.

Receiver Health

UINT8

Bit-masks

Bit 0 - if set, antenna line fault
is detected.

Bit 1 - if set, antenna line is
shorted; if not set, antenna line
is open. This bit is valid only if
Bit 0 is set.

Bit 2 - if set, the current fix is 2-
D; if not set, the fix is 3-D. This
bit is valid only if Receiver
Status Code byte is 0x00.

Bit 3 - if set, the current fix is
SBAS-corrected. This bit is valid
only if Receiver Status Code
byte is 0x00.

Bit 4 - if set, BBRAM was not
available at power-up.

Bit 5 - if set, Real-Time Clock
was not available at power-up.

Bit 6 - if set, the almanac stored
in the receiver is not complete
and current.

Bit 7 - if set, the measurement
clock bias is unknown.

20+N*12

Satellite ID

UINT8

1 to 32, or

120 to 138

Satellite PRN (GPS or SBAS).

21+N*12

Signal Strength

UINT8

0 to 55

Signal strength (in dB-Hz).

22+N*12

Acquisition Status

UINT16

Bit-masks

Bit 0 - if set, Doppler is valid.

Bit 1 - if set, code phase is valid.

Bit 2 - if set, time ambiguity is
resolved.

Bit 3 - if set, measurement is
valid.

Other bits are reserved.
