FLASH: On 2000-10-5 ~22:00Z, Station (antenna) moved to other wall of house for hopefully 10% better observations (but still not geodetic quality location).  Renamed to DWH1.

I am logging "continuous" GPS/GLONASS dual-frequency observables using a simple mast bracketed to my house (not geodetic quality location - see photo below).  Caveat: I am NOT a surveyor!

SEAW is a little over 16km to the SW.  DWH0's (ARP) ITRF96(1997.0) xyz is approximately -2280794.441 / -3638691.947 / 4700107.416

I log anytime I adjust the mast (only once so far), and I interrupt for firmware upgrades (see details of interruptions below).

Data is in files with names like dwh0xxx0.00d.z at ftp://ftp.niceties.com/pub/;
they include GLONASS and typically you'll want to gzip -d then crx2rnx to create 30-second epoch RINEX observation files (.00o).
I expect to keep the most recent couple weeks online (data is archived back to day 086 of 1999).
Feel free to email me a request for NAV files, or GPS-only data instead of the combined GPS/GLONASS data; gpsonly/dwh0xxx0.00o.gz are such files, and gpsonly/ashtech/dwhaxxx1.00o.gz are from collocated Z12 CGRS (usually since 11-JUN-2000 except few minutes daily during downloading, via antenna splitter).
Filenames like dwh0xxx0.00m.gz are Met files for a period when I had Paroscientific's MET3 sensor (I have a MET3A on order so they will resume someday).

Please limit your downloads, since I can be charged for excess transfers.

Antenna is dual-depth choke-ring (JPSREGANT_DD_E), L1/L2 phase center around .113M/.119M above ARP.
Oscillator is usually external 5MHz  HP 5071A-001 cesium steered ~+8.2e-14; what I call UTC(dwh).

Please report any problems you might encounter processing the RINEX, so that I can pass along to Javad.

I am trying to start a similar station I'll call tvb0 around N47 33 18, W122 8 26 (around 25km south) - it would be dual-frequency GPS/GLONASS but JPSLEGANT_E (small groundplane) on a home roof, hooked to standard like a Passive H-Maser (but not good environmental control).
