--------------------------------------------------------------------------

Your name and institution:
Contact email address(es):

Primary reference/paper for your approach (URL address or email attached):
Ge et. al. "Resolution of GPS carrier-phase ambiguities in precise point positioning (PPP) with daily observations", Journal of Geodesy

List of bias types considered and their temporal resolution:
UPDs in wide-lane and narrow-lane from daily observations, 5 min resolution

Clock corrections are generated at intervals of:
5 min

Ambiguity resolution for:
[X] undifferenced observations
[ ] between-satellite observations
[ ] other:


How do you select GPS code observable types (to be used for a specific
station)
if P1 and C1, or P2 and C2 are available?
Only P1 and P2

Do you generate integer phase clock corrections on a regular/operational
basis?
[ ] Yes
[X} No.


Recommendations for PPP users of your integer phase clock product:
None.

Do you have corresponding bias results available (in ASCII form)?
[ ] Yes
[X] No

Are there any specialties concerning your integer phase clock product?
None.

Extra question: Do you have experience/plans in extending your approach to
GLONASS observations?
[X] No expierience, but planning to implement it.
[ ] Yes, please specify:
