PSRDIFFSOURCE

Sets the pseudorange differential correction source

Platform:

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

This command determines what differential corrections the PSR and PDP (GLIDE) filters can use.

Differential corrections can be generated from RTK corrections. PSRDIFFSOURCE RTK enables this, allowing the PSR and PDP solutions to benefit from RTK corrections. An RTK-capable model is not required for this capability.

PSRDIFFSOURCE NONE stops any corrections from being used; the PSR and PDP solutions will revert to being uncorrected.

All types except NONE may revert to SBAS (if enabled) or SINGLE position types.

Message ID: 493

Abbreviated ASCII Syntax:

PSRDIFFSOURCE type [id]

Factory Default:

PSRDIFFSOURCE AUTO ANY

ASCII Examples:

1. Enable only SBAS:

   PSRDIFFSOURCE SBAS
   SBASCONTROL ENABLE AUTO

2. Enable differential from RTCM, with a fall-back to SBAS:

   PSRDIFFSOURCE RTCM ANY
   SBASCONTROL ENABLE AUTO

3. Disable all corrections:

   PSRDIFFSOURCE NONE

PSRDIFFSOURCE Type

Binary	ASCII	Description
0	RTCM	Use RTCM version 2 corrections from the given ID if available or SBAS otherwise. RTCM ID: 0 ≤ RTCM ID ≤ 1023 or ANY to accept all IDs.
1	RTCA	Use RTCA corrections from the given ID if available or SBAS otherwise. RTCA ID: A four-character string containing only alpha (a-z) or numeric characters (0-9) or ANY to accept all IDs.
5	SBAS	Use SBAS corrections such as WAAS, EGNOS and MSAS in the region they are available and applicable to. There are regions that are not covered by any SBAS satellite and so the solution will revert to uncorrected. The ID is ignored for this correction type.
6	RTK	Use differential corrections that are generated from RTK corrections if available or SBAS otherwise. The correction type used is determined by the setting of the RTKSOURCE command.
10	AUTO	Use any available correction source. If both differential and SBAS sources are available, differential will be preferred.
11	NONE	Disables all differential correction types. Solution will revert to uncorrected.
