Downlink Acquisition and Tracking Procedures for the ASCAMP Satellite Communications Terminal
Abstract
The advanced single-channel antijam man portable (ASCAMP) terminal was developed at MIT Uncoin Laboratory as a proof of concept for the Army's SCAMP terminal. The ASCAMP terminal is a 30-lb, extremely high frequency (EHF) satellite communications terminal capable of operating from 75 to 2,400 bps with low inclination, geosynchronous FLTSAT EHF package and Milstar satellites. The terminal was designed to be carried, set up, and operated by a single user. In many instances the control algorithms have been designed to compensate for simplifications made in the hardware to keep the terminal's size, weight, and power to a minimum. This report describes the procedures implemented in the ASCAMP terminal to locate the satellite and synchronize with its downlink. It contains descriptions of the timing and pointing requirements, the procedures for acquisition and tracking, and the measured performance.
