Navigation Solution
============================ navsoldef.txt ==================================
This file defines the columns of data in the navsol.log files produced by the
GRID software receiver. Each navsol.log file contains time-stamped navigation
solutions that represent the receiver's best estimate of position, velocity,
receiver clock error, and receiver clock error rate as calculated from data
provided by all participating receiver banks. See channeldef.txt for a
definition of ORT. ORT time stamps indicate the time at which the navigation
solution applies.
=============================================================================
Column Quantity
1 ----------- ORT week number.
2 ----------- ORT whole seconds of week.
3 ----------- ORT fractional second.
4,5,6 ------- X,Y,Z receiver antenna position expressed in meters the ECEF
reference frame.
7 ----------- deltRx, the receiver clock error expressed in equivalent meters.
True GPS time (TGT) is related to deltRx by TGT = ORT - deltRx.
8,9,10 ------ Xdot,Ydot,Zdot receiver antenna velocity relative to the ECEF
reference frame expressed in meters per second in the ECEF
frame.
11 ---------- deltRxdot, the receiver clock error rate expressed in equivalent
meters per second.
12 ---------- Flag returned from the navigation solver:
0 SOL_CONVERGED,
1 SOL_FAILED_TO_CONVERGE,
2 SOL_TOO_FEW_SVS_AFTER_PRUNING,
3 SOL_ITAR_VIOLATION,
4 SOL_CONVERGED_BUT_LARGE_RESIDUAL,
5 SOL_TOO_FEW_SVS
