I build a GPS disciplined oscillator and I need to set antenna coordinates in order to be able to operate it as accurately as possible.

What I need is a way to determine the geographic coordinates (in GPS reference frame) of a single fixed location (where the GPS antenna is placed).

This procedure will be done only once so:

  1. no point in buying expensive hardware (although rent is an option).
  2. hiring a professional to perform a single measurement, out of my budget.
  • Would a simple cellphone provide enough accuracy? – DPSSpatial Aug 27 '18 at 18:12
  • @DPSSpatial No. If it was the case, using the GPS module of the oscillator will be a simpler solution. Maybe averaging its output over a span of months can be enough. I don't know. – user3368561 Aug 27 '18 at 18:20
  • Could you use a well mapped feature, such as a survey mark? What sort of accuracy do you need? – Ian Turton Aug 27 '18 at 18:24
  • @IanTurton The time accuracy I'm targeting is < 10 ns. I don't know how to translate it to space domain, but due to GPS working mechanism, as more accurate I know antenna position more accurate will be my clock signal. – user3368561 Aug 27 '18 at 18:34
  • @IanTurton I'm not aware of any survey mark near my place, but there is a cell phone antenna relatively close. If they are precisely geolocated and I have a way to access this info maybe I can use it in some way. – user3368561 Aug 27 '18 at 18:36
