GPS H-250 Handset with Frequency Hopping / Rolling Code Encryption for Military Manpack Radios

GPS H250 Handset w/ Rolling Code Military Grade Encryption


Midian Electronics' TVS-2V-HS1G is a GPS handset with a military grade rolling code voice encryption. When the GPS H250 handset is keyed it will send the PTT Id (ANI) and the GPS coordinates. The unit also supports sending of an Emergency ID with Location when activated by the Man-Down - Lone Worker sensor. Midian's CAD-800 base controller decodes and displays the PTT ID along with the GPS location and other selectable information shown on a map using Google Earth or Terrain Navigator Pro with no monthly subscriber fees.

Midian's TVS-2V offers higher security than competitive rolling code voice encryption by using true frequency hopping rather than frequency sweeping. While competitive rolling code scramblers claim up to 1,000 hops per second, each of these hops are only a cycle or two in length. Midian's TVS-2V hops 6 to 12 times per second in standard mode and 13 to 25 times per second in advanced mode. Each hop is several hundred cycles in length.
