- Hello,
- Here are some questions about the antique NNSS (Navy Navigational
- Satellite System), or Transit, receiving equipment.
-
- I am a Ph.D. student working on an ionospheric-geodetic project.
- I am working with NNSS (Navy Navigational Satellite System) receivers
- that cause some problems. The equipment consists of 8 geodetic NNSS
- (2 CMA-751 and 6 CMA-761) receivers, all built by the Canadian
- Marconi Company.
-
- I am facing problems loading programs in the CPU's of the receivers.
- The software is stored on digital cassette tapes which were recorded
- about 10 years ago. The information has faded and reading the tapes
- causes checksum errors.
-
- Can anyone help me with the following questions:
- 1 How to obtain the programs CMA-751.000.X, 751.004.X, 761.201.X, and
- 761.210.X (X is wildcard), in any code?
- 2 Can you give me some information on the IM6100 CPU that is built
- in the receivers (compiler, manufacturer etc) ?
- You would help me greatly,
-
