NOTE
This checklist is the controlling crew document for the ISS-ULF2 rendezvous and separation.
The Rendezvous Timeline begins at Ti -3:00 hr and continues through docking. This is a
complete stand-alone document. The Separation Timeline begins 45 min prior to undock and
continues through 1:15 after undock. The undock/separation profile assumes a subsequent
ejectable deploy of the Pico Sat satellite.
Timeline pages assume an FD3 rendezvous and undocking on FD14. Lighting is based on
planned rendezvous altitude of 205 nm. Targeting I-Loads are based on 210 nm.

RNDZ BURN SOLUTION SELECTION GUIDELINES
BURN SOLUTION PRIORITY
All burns prior to, but not including, NCC 1) Ground solution
NCC & Ti 1) Onboard FLTR solution if STRK or RR
NAV converged
below)
2) Onboard FLTR solution if it agrees with
ground solution
3) Onboard PROP solution if it agrees with
ground solution
4) Ground solution
Post-Ti midcourse corrections 1) Onboard solution
* (for COAS, use step 2
**
*For the purpose of burn solution selection, NAV is converged if for the present sensor in
acquisition (RR or STRK), at least 40 marks have been accepted with state vector position
update of less than 0.5 Kft for at least the last 4 marks; or if state vector updates are small
and stable. These criteria do not apply to COAS NAV
**Burn solutions are considered to be in agreement if delta Vs differ by no more than the
‘final-ground’ limits for each axis
RNDZ BURN ENGINE SELECTION GUIDELINES
DELTA V ENGINE
< 4 fps RCS – Primary technique is multi-axis
4 to 6 fps RCS – Primary technique is +X
> 6 fps OMS – Single engine
