Defense Support Program (DSP) Satellites
DSP is a program of the U.S. Air
Force that operates the
reconnaissance satellites which
form the principal component of
the Satellite Early Warning
System currently used by the
United States.

IKONOS is a commercial earth
observation satellite, and was the first
to collect publicly available high-

resolution. It offers multispectral (MS)
and panchromatic (PAN) imagery

The Wide Area Augmentation System
(WAAS) is an air navigation aid developed by
the Federal Aviation Administration to augment
the Global Positioning System (GPS), with the
goal of improving its accuracy, integrity, and
availability. Essentially, WAAS is intended to
enable aircraft to rely on GPS for all phases of
flight, including precision approaches to any
airport within its coverage area
The Local Area Augmentation
System (LAAS) is an all-weather
aircraft landing system based on real-
time differential correction of the
GPS signal. Local reference receivers
located around the airport send data
to a central location at the airport.

REDWOOD CITY, Calif. (AP) - Satellite
navigation devices used to track Scott Peterson's
car after his wife's disappearance sometimes
developed glitches, once indicating he was
driving 30,000 mph.

JOINT DIRECT ATTACK MUNITION PROGRAM
The Joint Direct Attack Munition program (JDAM) was born from Operation Desert Storm shortfall.
Eventhough the Persian Gulf War was dubbed as the first ‘space war’, the precision guided bombs used produced a dismal results. Only 40% of the bombs dropped hit the intended targets.

Horror stories of these smart bombs gone astray are not new
and well documented.
Questions are being asked how smart and accurate are these
bombs?
Collateral damage is damage that is unintended or incidental
to the intended outcome.
The term originated in the United States military, but it has
since expanded into broader use.

CAMPAIGN FLIGHTS OVER 78 DAYS OF WAR.

BOMBING BLUNDERS (YUGOSLAVIA WAR)
5 APRIL: HOMES HIT.
CAUSE OF ERROR:
MISSILES FALL SHORT
First major NATO blunder when
an attack on a barracks resulted
in missiles striking a residential
area.Three missiles fell 600m
short of their target.

BOMBING BLUNDERS (YUGOSLAVIA WAR)
12 APRIL: TRAIN DESTROYED.
CAUSE OF ERROR: TIMING
NATO raid on a railway bridge hit a
passenger train, killing 10. The
Belgrade-Salonika train had been
crossing the bridge near Leskovac,
southern Serbia as the air-launched
missile released several miles away
reached its target."You can see if you
were focusing right on your job as a
pilot how suddenly that train
appeared. It was really unfortunate."

7 MAY: CHINESE EMBASSY HIT
CAUSE OF ERROR: MISTAKEN IDENTITY
In the biggest mistake of the campaign
to date, Washington admitted that an
out-of-date map used by its intelligence
operations had led Nato to launch
missiles at the Chinese embassy in
Belgrade, killing three people, injuring a
further 20. Nato said that the intended
target had been the Yugoslav Federal
directorate of Supply and Procurement
200 yards away.

US SOLDIERS KILLED BY B-52 BOMB
Three American special forces killed when
an American B-52 aircraft accidentally
bombed them.
US Central Command said five Afghan
anti-Taleban fighters had also been killed
when the 900-kilogram smart bomb was
dropped north of the Taleban stronghold of
Kandahar.
US Joint Chief of Staff John Stufflebeem
told reporters that the bomb dropped about
100m from the US troops who were under
heavy fire from Taleban forces at the time.

Mumbai Terrorist Attack
There has been approach to the High Court seeking a ban on
Google Earth, Wikimapia and other sites not blessed by Indian
security officials.
The petition states that Google Earth is against the objective of
the Indian National Security Act since the website gives users
‘minute details’ and provides photographs, as well as
‘extremely accurate navigational coordinates’.

"The difference in, or lack of, pixelation of images of the military
facilities compared to the surrounding areas will make it easy for
visual identification." In his written reply to Datuk Dr James Dawos
Mamit (BN-Mambong), Najib said the images were provided
worldwide commercially.
Malaysia will not ask Google Earth to
blur images of the country’s military
facilities to avoid terrorist attacks.
Defense Minister Datuk Seri Najib
Razak said doing so would indirectly
pin-point their location anyway.
