1. A system for processing navigation information from positioning signals comprising:

  • a measurement platform powered by a first power source comprising a positioning signal receiver comprising an antenna and downconverter configured to receive positioning signals and generate positioning data for multiple channels;

    a channel unit coupled to the positioning signal receiver and configured to receive in real time the positioning data for multiple channels, perform time critical intermediate positioning calculations at a time critical rate, generate intermediate positioning data and transmit the intermediate positioning data; and

    a user platform external to the measurement platform and powered by a second power source comprising a general purpose processing system bi-directionally communicatively coupled to the channel unit, the processing system receiving the intermediate positioning data from the channel unit of the measurement platform and calculating the position information from the intermediate positioning data, wherein the general purpose processing system is user programmable to execute applications utilizing the intermediate positioning data in a multitask environment concurrently together with other user applications.
