Peak-Seeking Controller for Real-Time Mobile Satellite Tracking [PDF]

, 2012
Increasingly tightened restrictions on antenna beam-width force the use of higher performance hardware in gimbaled satellite communication transceivers. The need for more precise hardware is forcing the price of gimbal-mounted satellites antennas higher.

Assessing performance of Bayesian state-space models fit to Argos Satellite telemetry locations processed with Kalman Filtering [PDF]

, 2014
Argos recently implemented a new algorithm to calculate locations of satellite-tracked animals that uses a Kalman filter (KF). The KF algorithm is reported to increase the number and accuracy of estimated positions over the traditional Least Squares (LS)
