66 -- UPGRADE/REPLACEMENT OF EXISTING CLOUD TO GROUND LIGHTING DETECTION SYSTEM ON THE NEVADA TEST SITE SOL 52ABNF-0-00068 DUE 072800 POC Abram Vinikoor (206)526-4395 E-MAIL: Click here to contact the Contract Specialist via, Abram.L.Vinikoor@noaa.gov. This publication serves as notice of intent to issue a sole source contract to Global Atmospherics Inc., Tucson, Arizona to upgrade the Lightning Location & Protection (LLP) System for NOAA's Air Resources Laboratory/Special Operations and Research Division (ARL/SORD), Las Vegas, Nevada. ARL/SORD provides support to the U.S. Department of Energy, Nevada Operations Office, at the Nevada Test Site (NTS) and elsewhere. The LLP System consists of Advanced Lightning Direction Finders (ALDFs) located on or near the NTS and an Advance Position Analyzer (APA). The following equipment is required for the LLP System Upgrade: 1) Upgrade five ALDF Model 141 Sensors to IMPACT-ES Sensors with the latest hardware and software. IMPACT-ES lightning sensors detect the presence of cloud-to-ground lightning events by employing both electric and magnetic field sensing. This combination of technologies provides the most accurate estimates of location and peak currents of cloud-to-ground lightning discharges. These upgraded sensors will improve existing ALDFs in sensor detection efficiency, angular accuracies, throughput: flash stokes; and concurrent flash processing. 2) Upgrade the APA280 Series Model 281 to APA 2000 Series, consisting of the LP2010 module with FALLS software. The LP2010 performs as the central analyzer for data collected by wide area sensors. The contract will include installation, training, site survey services, and priced options for spares and software. The design of this system is proprietary to Global Atmospherics Inc. The Government knows of no other system on the market that will independently provide lightning data that is physically, electrically, and functionally compatible to the existing ARL/SORD LLP System. This notice of intent is not a request for competitive proposals. See Note #22. Posted 06/28/00 (W-SN469488). (0180)
