We are looking into time sharing between GPS and cellular and what kind of performance we can have when switching the RF resources between GPS and 4G.
Looking through the Product technical specification for HL7800 it mentions time to first fix for hot and cold starts. For hot start, it says the typical value is 2s. Let’s say we were to switch between GPS and 4G a few times every minute, and that we had acquired a fix and GPS position previously, would the hot start then be applicable, i.e. it would take ~2s to get a fix for the GPS?
Are there any similar delays related to switching back to 4G as well (for instance if it is possible the connection to the base station was lost after having been in GPS mode for a few seconds)?
Do you have any tips on how we can test this performance? Do you possibly have some sort of bash script or C program available to download that shows how to do this time sharing efficiently?
