I am new to the surveying community and I hope you can help me with my problem. My colleagues and I are working at a university (geography) and we are doing research with GIS and remote sensing methods. For a research project in Tanzania and the Comores it is necessary to do some high precision surveying. We are used to do this in Europe with some known reference points and a base/rover system (postprocessing). It is a Magellan Promark 3.
Our problem now is, that we will have no reference points in the two countries available. And by our own measurements, we know that the accuracy of our base station is about +/- 2 meters (horizontal). What can we do to improve the accuracy without reference points? Are there reference stations available (haven't found any information yet).
Thanks,
Felix

Hi ePalmetto,
thanks for your fast reply. I will have a closer look on AFREF - this looks promising, thanks.
I took OPUS (and AUSPOS) in consideration, but since the Promark 3 provides only single frequency (i should have posted this earlier) it is not working for us.
ok, I found for a station in Kenya IGS RINEX data (http://igscb.jpl.nasa.gov/components/data.html). I am not sure how long the baseline can be, to use the data for correction (especially for single frequency revievers). Has anyone experience IGS Data? Any kind of manual would be magnificent.
thx a lot
you may be able to use reference points in Kenya..let me see what I can dig up
