ID>,<NumberSubframes>,<TimeOfWeek>,<WeekNumber>

Queries a sensitivity assistance message for a specific satellite (SV ID) and at given

specific time (Time of Week).

Query parameters:

<SV ID> The SV ID is the ID of the space vehicle for which the sensitivity

assistance data is queried.

Range: 1 to 37

<NumberSubframes> The Number of Subframes determines the length of the sensitivity

assistance data to be generated.

The maximum length of the generated sensitivity assistance data

is then 125 subframes, i.e. 25 pages or one complete navigation

message.

Range: 1 to 125

<TimeOfWeek> modulo 6 values greater than 0

Sets the starting time and date of the generated sensitivity assis-

tance data as GPS TOW (Time of Week).

The modulo 6 requirement is due to the fact, that the duration of

one subframe is 6 sec. For Time of Week values that do not fulfill

this rule, the calculation is made with the first lower modulo 6

value.
