Lockheed Martin AN/FPS-117 Radar
(General Electric AN/FPS-117)
FPS-117 is long-range early warning system radar's for U.S., NATO and Allied forces currently used by 16 countries. It has modular structure, there is no single point of failure. If one component fails, the whole thing will not become unserviceable. The system, which can be assembled or dismantled in four to eight hours, can be installed on a tower or mounted on a trailer and moved around. It can also diagnose its own problems, each of which takes an average of 30 minutes to fix.
- Doppler-type aircraft surveillance radar
- 3D radar scanning for greater accuracy
- 30 km maximum altitude for search
- 300 km maximum range
Croatia purchased five long-range, dual-use FPS-117E(1)T radar's with associated display consoles and five Monopulse Secondary Surveillance Radar's. Also included are three operations centers equipped with large-screen displays and air space management consoles.
from 'Spectrum Reallocation Cost Impacts: OBRA-93' 139.0 - 140.5 MHz and 141.5 - 143.0 MHz
"AN/FPS-117. The AN/FPS-117 has a surveillance (air defense warning) mission. The radar is designed to operate on twenty frequencies (channels) up to 1400 MHz, in both peacetime and crisis situations. Loss of channels results in degraded radar performance, potentially creating gaps in radar coverage of North America and jeopardizing the NORAD Integrated Tactical Attack and Warning Assessment system’s mission. Currently channels 1,16, and 20 are not used at all AN/FPS-117 sites, in order to prevent interference with other systems. Some sites have additional channels unavailable due to site-specific interference concerns. The following actions are necessary, as a result of OBRA-93, to alleviate concerns over the implications of secondary use of the spectrum, even at remote sites:
· Transmission requirements. Software modifications for a frequency synthesizer will be required to preclude the use of the reallocated channels and to retain the radar’s operational capabilities within the remaining band.
· Reception requirements. A hardware modification will be required to replace the frequency oscillators with a frequency synthesizer and to prevent use of the 1390-1400 band segment.
· Mission requirements. Target detection will not be affected by civil sources transmitting in 1390-1400 MHz; however, commercial sources may be reported as false detection's. If this occurs, a hardware modification will be required to eliminate the problem.
· Calibration and Maintenance Requirements. The loss of 1390-1400 MHz will require modification of the software used for calibration, monitoring, and fault isolation.
If replacement of major system components becomes necessary because the remainder of the band cannot accommodate mission requirements, costs are estimated at $350M. Past availability of the existing high-power, solid-state devices has lent itself to cost effective component savings and extended the system’s useful life. This is in direct correlation with preserving the mission requirement of Operational Availability with a minimal attended maintenance savings concept."
PRESS RELEASE
FOREIGN PRESS BUREAU ZAGREB
Evening Bulletin - No. 116/99
June 9, 1999CONTRACT SIGNED FOR NEW RADAR SYSTEMS FOR BETTER CONTROL OF AIR SPACE
An agreement was signed on Tuesday in the Croatian Defense Ministry, between the Defense Ministry and Lockheed Martin company, for the purchase of FPS-117 radar systems. The agreement was signed by the Assistant Minister for Equipping the Armed Forces, General-major Vladimir Zagorec and Manager of Lockheed Martin, Robert Ostowski.
Croatia’s Defense Minister, Pavao Miljavac, Chief-of-staff of the Croatian Armed Forces Headquarters, Davor Domazet, US Ambassador to Croatia, William Montgomery, and President of Lockheed Martin for Europe, Robert Clifford, were all present at the signing.
Speaking at a press conference following the signing, the Croatian Defense Minister stated that the signing is a continuation off the programme for organizing the Croatian Armed Forces. The agreement pertains to the purchase of five systems, which have dual functioning. This means that they can be used for military and for civilian purposes. The system is compatible to all NATO systems and satisfies the requirements of Euro Control 2000. The system was purchased in concordance with a favorable credit arrangement, stated the Minister, with the total cost of 94 million US dollars which will be paid off at an interest rate of less than 6 percent over 12 years. The system will be delivered within 18 months and will be ready for use within two years.
