SENSYTECH
SenSyTech, Inc., a leading developer of electronics and technology solutions for military,
intelligence and commercial markets, resulted from the 1998 merger of Daedalus
Enterprises, founded in 1968, and S.T. Research Corporation, founded in 1972.
S.T. Research provided communications signals intelligence and passive electronic warfare
systems, while Daedalus Enterprises added airborne imaging systems and services.

AHS Data System Design
The hardware / software system developed for the
AHS has now been migrated to our entire product
line of airborne remote sensors.

•
ABS – 2 spectral bands
AMS – 10 to 16 spectral bands
ATM – 11 to 16 spectral bands
AHS – 50 to 80 spectral bands
AMDC - camera based (2D array) products.

Sensytech Real Time Mapping
• Sensytech has been orthorectifying our
own airborne imagery using post
processing techniques for about 5 years
• Using the AHS system architecture we
have developed the ability to orthorectify
and transmit imagery in real time for
emergency response situations
• Following is a brief explanation of the
process and some examples of the results
Real Time Geocoding and Rendering
• Based on PARGE (Parametric Geocoding Procedure)
developed by Schlapfer, University of Zurich, and
Richter, DLR
• Vector Calibration
• Computes 3D vector for each pixel using sensor head geometry,
geometric calibration information previously recorded, and
Applanix position and orientation data at the image capture time
• Vector DEM Intercept
• Determines the intercept of the 3D pixel vector and the DEM
surface
• Image and Geocode Combiner
• Maps each raw data pixel to the geocoded image
Raw Image with no Correction
Collected in Ann Arbor, MI, Feb. 2004
OrthoRectified
Here the line scanner image has been chopped into 4 frames and geocoded
in near real time. Geocoding, classification, rendering, and air to ground
transmission of each frame occur in parallel with acquisition of the
subsequent frames.
Data Transmission Options
• Freewave
• 900 MHz - 70 Kbits/second - Line of Site – 60 miles
• $8K Installed
• RIPCom
• 2.4 GHz - 1 Mbits/second - Line of Site – 10 miles
• $12K Installed
• Inmarsat
• Pentastar Aviation has recently been granted an STC for a 256
Kbit/second Inmarsat system in a Gulfstream Aircraft
• $200K Installed
Freewave, RIPCom and other air to ground systems are inexpensive but
are short range. Inmarsat is expensive but has a wide range.
The AHS system architecture uses TCP/IP Ethernet allowing
us to integrate the highest performance to cost ratio
solution based on the specific needs of the application
GIS Compatible Thermal Imagery
The image shows an extreme test where the aircraft makes a 180 degree
turn while collecting imagery. Of course we would never do that in real life
but it makes for a great test of the Real Time Mapping System!
