Log Format
This is to specify which information will be recorded for each way point.
•
Normally, UTC, latitude, longitude, valid, speed and RCR should be chosen.
Therefore, the number of recorded data is estimated to be about 74,000 points.
•
ELEVATION, AZIMUTH and SNR can only be checked when SID is checked.
Mili-second
MS
Record method: Speed/ Time/ Distance/ Push Button
RCR
Signal to Noise Ratio
SNR
Line-Of-Sight angle of the satellite
AZIMUTH
The elevation of the satellite

SPEED
The altitude of a place above sea level or ground level.
HEIGHT
An east/west measurement of position in relation to the Prime
Meridian, an imaginary circle that passes through the north and
south poles.
LONGITUDE
A north/south measurement of position perpendicular to the earth's
polar axis.
LATITUDE
Data fix or not
