[FOSS-GPS] Ephemeris storage, how to purge it in RTKLIB and RTKnavi

[David Kelley]

I have basic problem using RTKLIB to ask of the list.   That is: where 
does RTKLIB  (RTKnavi in this case) keep the current broadcast ephemeris 
(orbital) data it is using?

The tool will cache any recent ephemeris data it gets a hold of and 
reuse that on subsequent  runs.  So, if you happened be connected to any 
stream that sends this data (many NTRIP casters do not - presuming your 
local rover will provide it for you) it all works fine.  And the default 
behavior is to take this data from any of base/rover/corrections streams 
(see Options, Misc Tab, "Nav Msgs Selection" drop down).   You many not 
even notice that a new data stream you are using does not provide the 
ephemeris updates until the prior ones time out.  And all of this is a 
different problem from downloading the data for precise or broadcast 
data from a web or FTP site (where the default location is C:\Temp).  It 
creates a file cache somewhere with this but even with scaning the whole 
PC for time stamps I can not find it.

I need to find this file and remove it between every test run, but 
frankly I can not find it anywhere.  Help.
