Imitation of GNSS signal


In today's world the use of simulators SNA signals is a common practice in the development, production, use and support of satellite equipment customers.

Due to signals simulator satellite equipment manufacturers are able to:

  • simulate the satellite signals to a variety of operating conditions;
  • conduct a full control the execution of scenarios for different types of tests to ensure reliability of the results;
  • simulate the repeated movement on the same route, with the same configuration of the satellite constellation.

Undoubtedly, this is a significant advantage over the conduct of trials in the «field» conditions.

Also, signal simulators provide the ability to assess the characteristics of the claimed manufacturers of navigation equipment, which is quite difficult to perform in the real conditions.
