  • LOS Downlink Systems

    Both systems are base upon commercial of the shelf technology.900 MHz System based upon Freewave Technologies equipment.2.4 GHz System based upon technology developed by Avarion.

  • 900 MHz Downlink SystemSystem utilizes a 902 928 MHz Freewave Technologies 115kBs radio modem and a 5 watt amplifier. This system will link with any computer network, including point-to-point ftp, or a laptop depending upon the needs of incident personnel, with a ground station installed.The distance between aircraft and ground station could be as far as 100 miles line-of-sight.GROUND STATION

  • Freewave setup Tok, Alaska

  • Why 2 Systems? RIPComm\Freewave Comparison

  • Remote Internet Protocol Communication System RIPComDeveloped by NASA Goddard Space Flight CenterAs with 900 Mhz system can be used with a computer network or a single lap top.

  • NIFC Ground and Field testsField test were conducted by NASA-GSFC, NIFC, and RSAC personnel 3/14 3/17.Tests were extremely successful. 3.2 Mbs downloads are possible at 10,000 ft AGL, with a range 9 miles.We were able to conduct downloads at ranges up to 15 miles. (Approximately 500 kbs)System is able to tolerate transmission interruptions of up to 45 seconds with out affecting the file transfer.

  • Field Tests The next step is to utilize the system during actual incidents. This will happen early in the 2003 fire season. After successful completion of these tests several systems will be deployed for operational use.

    Dedicated Flight TestingNOT assigned as an IRINAbility to follow jet and test in a number of situations

    First goal to demonstrate RIPCom to NIROPS (R4)
