Usually for post processing DGPS in any technique (RTK - Carrier phase, Pseudorange code) the RINEX files used contains data for many consecutive epochs. This leads to very large RINEX files.
Is it possible to apply those techniques for single epcoh? If not, does skipped series will work (thus if epoch is 1 seconds, so each 5th epoch will be recorded thus every 5 seconds)? For both cases, if it's possible, does the accuracy degraded?
The nature of the question is to understand whether the underlying differential GPS algorithm is has look ahead/behind buffer? [i-1, i, i+1].
