Objective
The aim of the project is to evaluate the new ratio position fixing system "navstar" for its suitability as an aid to offshore hydrocarbon exploration.
Navstar is a satellite based system funded by the U. S. Dept.
of Defence. It provides a 24 hour global position to an accuracy of approximately 100 metres together with velocity and atomic time output.
An instrumented bell jetranger helicopter has been flown with an onboard data aquisition system in conjunction with a microwave trisponder precision navigation aid. Loran c was also tested for it suitability as a comparator system.
The results from the trisponder system indicated an overall accuracy of plus or minus two metres and the loran c indicated plus or minus one hundred metres.
The loran c data will be used as an aid when post processing data as the output is in direct latitude/longitude rather than range /range as in the case of the trisponder. The tests completed so far confirm that the comparison system has sufficient resolution and accuracy to make possible accurate tests on the gps receiver when circumstances permit.
There are three major phases of the project.
A) selection of receivers and integration into test platforms (aircraft, boat).
Construction of special purpose data recording systems.
B) operational trials.
Establishment of a test range overland using microwave transponders.
Conduct flight trials over test range over water.
Conduct marine test.
C) analysis of data.
Computer printout of tracks and comparisons with other inputs such as mini-ranger loran c.
