International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents a history of telemetry at White Sands Missile Range, New Mexico. White Sands Missile Range is located in the Tularosa Basin between the San Andres and the Organ Mountains on the west and the Sacramento Mountains on the east. Designation of more than one million acres of New Mexico range land as a testing areas established White Sands Proving Ground on July 9, 1945 as the Birthplace of Americas Missile and Space activity. On July 16, 1945 the first Atomic Bomb was exploded at Trinity Site. Project Hermes began in November of 1944 with a contract to General Electric by the Ordnance Department to develop a long range guided missile for the Army. Missile testing began in September of 1945 with the firing of Tiny Tim missiles. The capture of German V2 rockets led to testing and firing V2s concurrently with the Hermes. The first two-stage rocket consisted of a WAC Corporal mounted on the nose of a V2. Bumper # 5 set flight records of 5,150 miles an hour and an altitude of 244 miles on February 24, 1949. The paper includes: *Chronological highlights of telemetering events. *Discussion of telemetry systems and events that occurred at WSPG/WSMR from 1944 through 1990. *Telemetry systems and events from 1990 to the present. *Planned future telemetry systems and probable future systems.

Since the attacks of September 11th, 2001 involving commercial aircraft used as missiles to attack critical assets located within the United States, the U.S has worked diligently to enhance its military air defense posture. Air defense of critical U.S. assets and National Special Security Events (NSSE) have been enhanced by adding static and proposed deployable Ground Based Air Defense (GBAD) systems designed to provide a [beta]last line[gamma] of defense from air attacks over U.S. soil. Currently this last line of defense is incorporated with the air and maritime military air defense forces providing a [beta]defense in depth[gamma] over critical assets, but does not support the air and maritime air defense over broader ranges of U.S. soil where critical assets do not exist. As the U.S. continues to enhance its air defense posture around critical assets and high priority events against terrorist attacks from the air, it is reasonable to assume that the terrorists may adjust their strategy for air attacks. The terrorists may deem it more beneficial to attack targets which lack a last line defense. It is therefore critical to examine new means and methods to provide GBAD in areas which may be determined to be less lucrative targets. In addition to the proposed alternate terrorist strategy, it is also reasonable to assume that increased security measures in the Transportation Security Administration (TSA) will deter the terrorists from attempting another hijacking event; thus forcing them to seek other means of attack. Cruise missiles (CM) are a cheap and effective means of causing limited destruction. Cruise missiles can be programmed to maneuver and operate at various altitudes and are small enough to be transported with little to no visibility. A cruise missile in the wrong hands could find its way to within miles of the U.S. borders and coastlines. If launched; a cruise missile could engage random targets throughout the U.S., such as malls or schools, and cause a major upset to our national security. Therefore, a defense system should be established which incorporates GBAD that is capable of engaging the CM threat with little to no notice, over the entire U.S. border and coastal regions.

Angles measurements from optical systems are the primary source of data for maintaining the orbits of high altitude satellites. Radar measurements are used primarily for low Earth orbit (LEO) satellites. Recently it has been shown that the accuracy of the orbit updates using only optical system angles-only data is just as good, if not better, than the performance from radar systems for LEO satellites. The purpose of this thesis is to investigate the use of optical angles data with and without laser ranging data in determining the trajectories of missiles. Analytical Graphics, Inc. Satellite Tool Kit is used to model the trajectory of a ballistic missile. Several scenarios are developed for determining the orbit when acquired by sensors providing various combinations of range, range rate and angles data. It is found that the combination of range, azimuth and elevation sensor data yields an orbit determination that has enough merit to be called accurate. The error of the orbit determined by the angles-only data is two orders of magnitude larger than the error of the range and angles measurement. Additionally completed was an analysis of what would happen if the sensors could only track to the maximum altitude of the orbit. As was assumed, the known position of the object drifts ranged from minimal to significant predicated on the final known position. This is indicated by the error ellipsoid. It was again found that the combination of range, azimuth and elevation sensor data until the maximum altitude yields an orbit determination that has enough merit to be called accurate. Also considered was the addition of a second sensor that had the capacity to always track range, azimuth and elevation to increase the time that is afforded to track the object, increasing the overall accuracy of the orbit determination. It is found that the addition of a second sensor increases the fidelity of the angles-only measurement such that the combination of azimuth and elevation sensor data yields an orbit determination that has enough merit to be called accurate.
