COBRA BRASS family of sensors
For some years, there have been various discussions about the COBRA
BRASS sensor, http://www.fas.org/spp/military/prog...cobrabrass.htm It's been thought/speculated that, in addition to the one that apparently went up on the NRO's CAPRICORN satellite in January 1998, there were others, probably on the Titan Launch Dispensers that carried the Navy's NOSS-2 triads into orbit and then went into MEO. It turns out that the Naval Postgraduate School site has some items that pretty clearly establish that COBRA BRASS is a series of sensors and imply a bit about what it does. ------------------------------------------------------ http://web.nps.navy.mil/~code09/Thes...abs%20fy97.pdf COBRA BRASS FOR BATTLESPACE CHARACTERIZATION AND BATTLE DAMAGE ASSESSMENT (U) William Mitchell Darling-Lieutenant, United States Navy B.S., Purdue University, 1986 Master of Science in Systems Technology - March 1997 Advisor: Dan C. Boger, Command, Control, and Communications Academic Group Second Reader: Kyle T. Alfriend, Navy Tactical Exploitation of National Capabilities (TENCAP) Chair Battlespace characterization and battle damage assessment are important to the warfighter and must be a part of the strike planning. The Cobra Brass research and development sensor has the capability to provide information the warfighter canuse to aid in his decision making. Navy TENCAP is using Cobra Brass in an operational mode to test the feasibility of operationally tasking this type of sensor. This thesis educates the warfighter on the Cobra Brass family of sensors, investigates the utility of Cobra Brass for battlespace characterization and battle damage assessment, and develops a concept of operations for the non- imaging infrared sensors presently deployed and for future such sensors. ------------------------------------------------------ http://web.nps.navy.mil/~code09/Rese...0ph%20proj.pdf CENTRAL MASINT ORGANIZATION R&D TECHNICAL ASSISTANCE R. Chris Olsen, Associate Professor Department of Physics Sponsor: Defense Intelligence Agency OBJECTIVE: The proposed effort is to support the Central MASINT organization in its research and development efforts, particularly in the area of spectral imagery and high frame rate non-imaging infrared systems. Technical development of the Cobra Brass F System, exploitation of Cobra Brass F data and development of a UV spectral imager are supported. SUMMARY: Significant progress was made with the Cobra Brass studies, including work in target tracking and aerosol discrimination. Work on a new UV spectrometer was begun. A two-day workshop was held on the problem of detecting chemical and biological agents.

Olsen, Associate Professor Department of Phyics Sponsors: U.S. Geological Survey and Naval Postgraduate School OBJECTIVE: The proposal is to enhance model based ash drift forecasts using near real time observations. Products derived from classified and unclassified systems will be used to provide model input. Campaign strategies will be developed for acquisition of necessary "ground truth" information. SUMMARY: Volcanic ash clouds are a hazard for civil and military aircraft. The ability to identify boundaries of hazardous regions requires both observations and models of ash cloud behavior. In the first year of study, data from the AVHRR sensor were acquired for volcanic events on the Kamchatka peninsula. Software was developed for the analyis of such data in order to distinguish between ash and water clouds. These data were compared with observations from national systems, which showed agreement at some times, but "false alarms" at others. The Cobra Brass sensor launched in late 1997 will provide a complementary data set which should enable real-time warnings and model input. Analysis of Cobra Brass data will begin in 1998.

COBRA BRASS family of sensors
Technical development of the Cobra Brass F System,
exploration of Cobra Brass E data and development of a UV Spectral imager are supported. The Cobra Brass sensor launched in late 1997 will provide a complementary data set It appears that Cobra Brass E was the sensor on the NRO CAPRICORN/USA 137 satellite launched on 29 January 1998 (http://www.astronautix.com/craft/capicorn.htm) Note that the inferred existence of CB A,B,C and D is consistent with the speculation that they are carried on the NOSS-2 A/TLD/SLDCOM hosts (three in orbit, one lost in a launch accident). http://www.cambr.uidaho.edu/news/spacecraft.asp Spacecraft With CAMBR Chips Center for Advanced Microelectronics and Biomolecular Research University of Idaho Updated January 2001 [snip] Cobra Brass - E / DOE CCSDS Lossless Data Compressor (USES) Rad Hard 1.2um Gate Array (UTMC) Reed Solomon CCSDS Telemetry Channel Coder (RS16e) Rad Hard 1.2um Gate Array (UTMC) Launched: Sometime 1997/early 1998 |
