Appendix C					Logs
				Table 16: Solution Status
		Solution Status			Description
	(Binary)		(ASCII)
0			SOL_COMPUTED		Solution computed
1			INSUFFICIENT_OBS		Insufficient observations
2			NO_CONVERGENCE		No convergence
3			SINGULARITY		Singularity at parameters matrix
4			COV_TRACE		Covariance trace exceeds maximum (trace > 1000 m)
5			TEST_DIST		Test distance exceeded (maximum of 3 rejections if
					distance > 10 km)
6			COLD_START		Not yet converged from cold start
7			V_H_LIMIT		Height or velocity limits exceeded (in accordance with
					export licensing restrictions)
8			VARIANCE		Variance exceeds limits
9			RESIDUALS		Residuals are too large
10			DELTA_POS		Delta position is too large
11			NEGATIVE_VAR		Negative variance
12			Reserved
13			INTEGRITY_WARNING		Large residuals make position unreliable
14-17			Reserved for SPAN-capable receivers
18			PENDING		When a FIX POSITION command is entered, the
					receiver computes its own position and determines if
					the fixed position is valid a
19			INVALID_FIX		The fixed position, entered using the FIX POSITION
					command, is not valid
20			UNAUTHORIZED		Position type is unauthorized - HP or XP on a receiver
					not authorized for it

a.PENDING implies there are not enough satellites being tracked to verify if the FIX POSITION entered into the receiver is valid. The receiver needs to be tracking two or more GPS satellites to perform this check. Under normal conditions you should only see PENDING for a few seconds on power up before the GPS receiver has locked onto its first few satellites. If your antenna is obstructed (or not plugged in) and you have entered a FIX POSITION command, then you may see PENDING indefinitely.
