Help for TIMSNAV
PURPOSE:
TIMSNAV adds NAV data to the TIMS Auxiliary file.
It requires two inputs, the TIMS Auxiliary file created with the 'ALL
option and the NAVLOG output file. The output is a new TIMS Auxiliary
file with eight additional fields (Radar Altitude, Pressure Altitude,
Total Air Temp, Dew Point, PRT-5, Wind Angle, Wind Speed, and Ground
Elevation) plus NAV data inserted into seven of the existing fields.
The data is stored as follows :
Samp Data
1 Ref Temp 1
2 Ref Temp 2
3-14 Data for 6 channels
15 Year
16 Month
17 Day
18 Hour

EXECUTION:
TIMSNAV (TIMS.AUX,NAV.INT) TIMS.NAV
METHOD:
TIMSNAV reads time from the TIMS data and uses the data for the
corresponding time in the NAV data. The TIMS time is typically given
in integer seconds even though data is taken up to 25 times a second.
When two consecutive times are the same, or inconsisent, TIMSNAV will
adjust the time according to the scanning speed to get fractional seconds.
It then finds the two times in the NAV data that cover this time
and interpolates between the data entries for the two times.
The TIMS time is sometimes missing (stored as zero) and TIMSNAV
uses the scanning speed to calculate the expected time.
However, if the time is missing at the beginning of the file, the
user must manually input it with the STIME option.
PARAMETERS:
STIME=(Hour, Minute, Second) must be used when start time is missing.
