ASSIGNALL

Assigns all channels of a satellite system

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

The ASSIGNALL command should only be used by advanced users.

This command is used to override the automatic satellite channel algorithms with manual instructions for all channels in a satellite system.

Message ID: 28

Abbreviated ASCII Syntax:

ASSIGNALL [system][state][prn [Doppler [Doppler window]]]

ASCII Example 1:

ASSIGNALL GLONASS IDLE

In example 1, all GLONASS channels are idled, essentially stopping the receiver from tracking GLONASS.

ASCII Example 2:

ASSIGNALL GLONASS AUTO

In example 2, all GLONASS channels are enabled in auto mode. This enables the receiver to automatically assign channels to track the available GLONASS satellites.

This command is the same as ASSIGN except that it affects all SV channels of the specified satellite system.

These command examples are only applicable to specific receiver models.

If the system field is used with this command and the receiver has no channels configured with that satellite system, the command is rejected.

GLONASS SVs cannot be assigned if there is no information on GLONASS frequencies and matching slot numbers.
