The GLONASS clock corrections you generate are consistent to:

[X] pseudorange
[x] carrier phase

Please mark both fields if indicated.

Clock corrections are generated at intervals of:


5 min.


Handling of GLONASS interfrequency code biases (for ionosphere-free LC):

[X] one bias parameter for each station and satellite combination/pair

[ ] one bias parameter for each station and frequency channel
combination/pair
[ ] other configuration:
Time resolution:


One value per day.


Description of datum definition (or reference) for GLONASS code biases:


GLONASS code biases constrained to zero for all reference clock/satellite pairs.


How many conditions/constraints are imposed for the bias datum definition?


Apriori constraints on non-reference station/satellite pairs is set to 100 m or
~1/3 microsec (1-sigma).


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


Standard use of P1 and P2. Use C1 if P1 unavailable. C2 is not used.


Do you generate GLONASS clock corrections on a regular/operational basis?

[X] Yes

[ } No, but test results (in clock-RINEX) would be available for:


Recommendations for PPP users of your GLONASS clock product:


None.


Do you have corresponding GLONASS bias results available (in ASCII form)?

[X] Yes

[ ] No

Are there any specialties concerning your GLONASS clock product?


Extra question: Do you have experience with GLONASS ambiguity resolution?

[X] No

[ ] Yes, please specify:
