Abstract : This report covers the development and engineering design tests of a prototype surveying instrument which utilizes inertial techniques for the determination of position, azimuth, elevation, and grid convergence. The Inertial Surveying Equipment (ISE) is essentially an inertial system which uses a special data correction technique to attain performance characteristics suitable for artillery surveys. The ISE can be used in either a ground vehicle or a helicopter. The report concludes that: (a) The prototype ISE, in system tests, demonstrated the feasibility of using an inertial system that incorporates a data refinement philosophy for performing surveys of 1-hour duration to an enroute accuracy of about 25 meters mean radial error in position. (b) The prototype ISE is not suitable for engineering tests because of the sensitivity of the computer subsystem to vibration and shock under dynamic test conditions. (c) Improvements in performance, reliability, and ease of operation and maintenance can be obtained in future equipment by optimizing stable platform performance, data refinement techniques, and gyroscope and integrator trimming procedures and by following good human engineering and reliability practices.
