tution instruments and information on their accuracies.
2. Ultra uide angle camera and auxiliary airborne instruments
An integrated system of airborne instrumentation for both
ultra uide and uide angle photography has been developed by
Wild during recent years. The individual items of equipment
for ultra uide angle photography are as follous:
- PAU2 Universal Mount, accepting the
- RC9 Super Hide Angle Camera equipped uith either the Super-
Aviogon or the Super Infragon lens, and the
- HC1 Horizon Camera;
- RST2 Recording Statoscope;
- (\JFI Navigation Sight;
- PNG1 Servo Control Unit, for remote control of the camera tip,
tilt and drift settings from the NF1 Navigation Sight.
This instrumentation is described in the Presented Paper "Neu
Integrated Airborne Instrumentation for Photogrammetry" (8).
3. HiId Instruments for preparation for mapping
PdCiSliOÎËlElËÎËÎiSn • For narma l mapping purposes (e.g. topo
graphical, geological), examination of contact prints or
diapositives in the ST4 Mirror Stereoscope under lx or 3x
magnification is sufficient for photo-interpretation, uhereas
enlargements made in the UG1 Enlarger are required for notation
in applications such as forestry and geographical studies.
Military applications require stereo interpretation on high-
resolution records (original negatives, diapositives) under
the greater magnifications possible uith the ST4 uith 8x
eyepieces or uith a Hild Stereomicroscope.
ÎEEÎiliEEÏiEO : The neuj ^ Enlarger-Rectifier replaces the
earlier model E3. Details of this instrument are given in
the Presented Paper by R.Scholl (9). The tip and tilt values
derived from Horizon Camera photographs can be made use of
in the rectification process.
