Set Differential GPS Corrections

This TSIP packet provides the delta differential corrections from RTCM-104 record type 2. There is no response to this packet. Scale factors are version 1 unless the version 2 flag is set. The format for this packet is shown in Table A-62.

Table A-62 Command Packet 0x61 Data Formats

Byte	Bit	Item	Type	Value	Definition
0 - 1		Modified Z-count	UINT16	0-5999	.6 SEC
2	0-6	Number of SVs		0-31
2	7	Version 2 flag	Bit	1	must be set
	The next 3 bytes are repeated as a group for each satellite:
3+(N*2)	0-4	SV PRN		0-31	"0" Is SV 32
3+(N*2)	5-7	Scale factor		0	Low Scale factor
					(.02m, .002 m/s)
				4	High Scale factor
					(.32m, .032 m/s)
				7	Correction not
					usable
4+(N*2)		Range correction	UINT16		RTCM-104

The units and scale factors are as defined by Packet 0x60. Delta range correction rates are not entered.
