Rendezvous Radar Question

[ADT187]

Hi Guys,

Having a bit of trouble with my Rendezvous radar during lunar ascent!

Managed to get through the Ascent checklist with a pretty decent P52 and roughly on timeline.
Have started P20 and seems to be tracking properly. However its not seeming to take any marks.

With a V16 N45 I get data I don't understand ( 0000, -0002, +04969) ... and can't seem to find an answer in any of the documentation.

Wonder if someone might be able to shed some light?

Cheers,

Alex

Which NASSP version are you on?

Also just opened your scenario, looks like you have a mark pending your accept, notice KEY REL is flashing? Press the KEY REL button and you will see a N49, this is because its a little larger than the expected threshold (normal for a first or second mark) and its asking you to "accept" it. Once you do the mark will be processed.

Also regarding your N45, because you are just calling it in P20, it's not being updated by P32-35, so the R2 and R3 data are meaningless to you currently.

Normally N45 is the following:

R1: Marks
R2: TFI Of Next or From Last Burn
R3: Middle Gimbal Angle for the burn

Again, since you are in ONLY P20 and not a rendezvous burn calculation program, calling N45 only will populate marks for you which is normal.
