Having decided I would get a good nights sleep knowing the GNSS kit will be working down here in these conditions I decided to unpack the Topcon HiPER HR’s and switch on the base and rover, now 2am….

The receivers found the required satellites (locked on to 18!) and within a few minutes were reporting a fixed solution. That was great feeling. There is no reason they should not do their job, but with radios and extreme temperatures it’s always better to “know”.

Now I could definitely sleep.
