on the LCD screen. Do not confuse this option with the
Format
option under Tracking, which
defines the format of position report to be transmitted to a NOC.
Use Position Model to formulate the static and dynamic characteristics of the GPS receiver. By
default, the portable model is used as it is suitable for most applications. However, for those
requiring functionality at high altitudes, speeds, or accelerations, select an alternate model.
Portable
(default setting): Suitable for most situations; for applications with low
accelerations; maximum altitude of 12 km; maximum velocity of 310 m/sec (1,116
km/h); maximum vertical velocity of 50 m/sec; sanity check type: altitude and velocity;
maximum position deviation: medium.
Stationary:
Used in timing applications (antenna must be stationary) or other
stationary applications; velocity is constrained to 0 m/s; zero dynamics assumed;
maximum altitude of 9 km; maximum velocity of 10 m/sec; maximum vertical velocity
of 6 m/sec; sanity check type: altitude and velocity; maximum position deviation: small.
