Subject:[RapidServiceMail] No.31: (HITU) Monument Peak (7110) Strange "decimal" range bias

********************************************************************************Dear Monument Peak Station,

Our daily analysis detected a very strange behaviour in Monument
Peak´s data obtained on 1 Aug. The bias values are mostly
overflowed in the analysis report:
http://geo.science.hit-u.ac.jp/slr/bias/ (click Latest Analysis Report)

Strangely, the post-fit residulals are close to 150 km, 15 km or 1.5 m,
in one way distance. These correspond to 1 ms, 100 microsec, and
10 ns in two way range. Perhaps one decimal digit is wrongly recorded
in or read from a timer. I do not know it is from hardware or software,
but I hope it will help you find the problem.

Best Regards,
Toshi
