MEMORANDUM FOR: Project Operations
ATTENTION:
SUBJECT:
Tracker Camera Mode
1. Recent discussion between HTA personnel and
your office has indicated the need for reconsideration
of a previous proposal.
2. It was suggested earlier that consideration be
given to the possibility of incorporating a new firing
mode into the Tracker camera operat-io.n. The new mode
would permit the tracker to fire In synchronization
with the main camera configuration during the time the
main cameras are operating (with the B camera as the
main configuration, the tracker would f'.re in synchro-
n-i_zation with the vertical position..)
3. The obvious benefit is to produce a method of
determining main camera attitude by comparison with
synchronously fired tracker exposures, which image
both horizons. Such attitude data is invaluable to HTA
analysts, and, at present, cannot be determined by any
other means.
4. Further discussion of this proposal with HTA
can be made at any time by contacting this offs
or the Technical Intelligence Branch,
ARTHUR C. LUNDAHL
Chief, Photo Intelligence Division, ORR
