Chapter 5 Commands
Syntax: Message ID: 27
Examples:
ASSIGN 0 ACTIVE 37 0 2000
ASSIGN 15 120 -250 0
ASSIGN 11 28 -250 0
The first example sets the first SV channel to acquire satellite PRN 37 in a range from -2000 Hz to +2000 Hz
until the satellite signal has been detected. SV channel 11 is set to acquire satellite PRN 28 at an offset of
-250 Hz only in the third example.

H 0
2 channel 0 to 15
SV channel number to apply the command
to. 0 is the first SV channel and 15 is the last:
16GPSL1L5: 0-7 for GPSL1 and
8-15 for GPSL5
10GALILEO6GPS: 0-9 for GALL1 and
10-15 for GPSL1

Page 120.
ULong 4 H
3 state See Table 18 below.
Optional desired SV channel state. If a value
is not given, the default of ACTIVE is used.
Enum 4 H+4
4 prn
0 to 37 for GPS
120 to 138 for GEO
0 to 50 for GAL
Optional satellite PRN code. A value is
required only when the state field is set to
ACTIVE.
Long 4 H+8
5 doppler -100 000 to 100 000
Optional current L1 Doppler offset of the
satellite specified in the prn field in Hz.
NOTE:Satellite motion, receiver antenna
motion, and receiver clock frequency error
must be included in the calculation of
Doppler frequency.
Long 4 H+12
6 window 0 to 10 000
Error or uncertainty in the L1 Doppler
estimate given in the doppler field, in Hz.
NOTE:This is a ± value. For example, enter
500 for ± 500 Hz.
ULong 4 H+16
ASCII Description
IDLE Set the SV channel to not track any satellites.
ACTIVE Set the SV channel active.
AUTO Tell the receiver to automatically assign PRN codes to channels.
