Satellite-to-Satellite Tracking and Satellite Gravity Gradiometry [PDF]

open access: yes, 2001
The purpose of satellite-to-satellite tracking (SST) and/or satellite gravity gradiometry (SGG) is to determine the gravitational field on and outside the Earth's surface from given gradients of the gravitational potential and/or the gravitational field at satellite altitude.

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

open access: yes, 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.
