I have been doing a lot of work in the last year on a ground station, my
part of which was to communicate with the Apache Longbow.  I was kind of
wandering around the net looking to see what info there was on the apache
longbow, and i found something that i thought might interest the team at

<http://www.lmco.com/MMMTI/Slide4.html>

the home page for this is at

<http://www.lmco.com/MMMTI/Home.html>

an quote from this page that relates to Ada is given on the end of this
message.

Since we are only a subcontractor on the groundstation work i don't feel i
can say a lot about it, other than it was done in Ada, completed on
time/budget, and had successful ground to air tests a couple weeks ago in
florida.

This outtake does not refer to my ground station work, but to the flight
software.  The Apache Longbow system is a very successful system that is
just now being fielded.  Boeing is raking in the orders for these puppy's.
perhaps someone on the team from martin marietta (Pages are from the radar
contractor MM) could get permission to use some pieces of this page to do
an Ada success story web page?

outtake from <http://www.lmco.com/MMMTI/Slide4.html>

"The Longbow Fire Control Radar (FCR) is a mast-mounted 35 GHz radar system
for the detection, location, classification, and prioritization of tactical
targets. Moving and stationary targets are automatically classified as
tracked vehicles, wheeled vehicles, air defense systems, helicopters, or
fixed-wing aircraft. A Radar Frequency Interferometer (RFI) is integrated
with the FCR for the passive detection, identification, and angular
location of hostile emitters. The mast-mounted antenna and rapid, large
area search minimize helicopter exposure time for target acquisition,
giving unprecedented survivability against even the fastest threat air
defense systems.

The FCR is designed to support two-level maintenance and consists of 44
electronic line replaceable modules (LRM) and 19 non-electronic LRMs. The
Mast-Mounted Assembly (MMA) houses the radar antenna, elevation gimbal,
solid-state transmitter, RF receiver, power supply/controller, azimuth
drive, and RFI antenna/receiver modules. The Low Power RF (LPRF), which
contains LRMs for waveform generation and down-conversion, and the
Programmable Signal Processor (PSP) are located in the helicopter's
extended forward avionics bays along with the RFI Processor. The FCR has
built-in-test (BIT) and fault-isolation modes which can isolate failures to
one of the 44 electronic LRMs with a 95 percent probability. Mission
software is coded in the Ada language to minimize software support costs."

  "DOS Computers ... are by far the most popular, with about 70
million machines in use worldwide. Macintosh fans, on the other
hand, may note that cockroaches are far more numerous than
humans, and that numbers alone do not denote a higher life
form." (New York Times, November 26, 1991)
