TL;DR: The Marine Aided Inertial Navigation System (MAINS) utilizes the frequent position fixes available from the aids to reduce the performance requirements and therefore the cost of the inertial unit.
Abstract: By combining the data from the radio aids with inertial data, using the central digital computers where available, navigation information of sufficient accuracy to satisfy the requirements of most missions can be obtained. The concept of using position fixes to aid and improve the performance of an inertial system has been demonstrated in manner, data received from LORAN and satellite aids with the inertial data. The Marine Aided Inertial Navigation System (MAINS) utilizes the frequent position fixes available from the aids to reduce the performance requirements and therefore the cost of the inertial unit.

TL;DR: In this paper, the authors surveyed factors that influence low level navigation and affect Army capability in conducting low level missions and the nature of improvements in equipment, procedures, and training needed to provide the Army with effective operational capability in low-level navigation were indicated.
Abstract: : Factors that influence low level navigation and affect Army capability in conducting low level missions were surveyed. The nature of improvements in equipment, procedures, and training needed to provide the Army with effective operational capability in low level navigation were indicated. Major conclusions from the survey include limited capability in low level aerial navigation as affecting future Army combat effectiveness; the rapid reaction mission over unfamiliar terrain in low level navigation; potential improvements in training or procedures for present navigation system and equipment; a simple automatic dead reckoning navigation computer in routine attainment of operationally effective low level navigation performance; and reorienting navigation procedures and training to simplified line of position navigation techniques.

TL;DR: A study which illustrated the feasibility of implementing an on-board aircraft navigation system based on using the A TS-1 and ATS-3 satellites, the modified Omega Position Location Equipment Control Center, and a suitable aircraft terminal was conducted.
Abstract: A study which illustrated the feasibility of implementing an on-board aircraft navigation system based on using the ATS-1 and ATS-3 satellites, the modified Omega Position Location Equipment (OPLE) Control Center, and a suitable aircraft terminal was conducted. The report provides: (1) a consideration of the problems of satellite navigation and an objective definition of the optimum system under the constraints of its specified components, (2) a description of the necessary modifications to the OPLE Control Center, the design of an aircraft terminal, and the design of ground reference terminals, and (3) an outline of an experiment plan and an estimate of the cost to be expected in conducting the program.
