Portable FOREMMS Work Station

Portable FOREMMS Work Station

 

Description of the work

 
Modify Handheld PCs to be suitable for field Work Stations, including GPS receiver, GSM phone, their antennas and power supply.
 
 
We have to deal with three different scenarios one of which must be chosen in later stage of the project:
 
  • First scenario
Handheld device, detached from the rest of the equipment and connected to via two RS-232 serial communication ports with a cable cord.
 
 
The equipment detached from the handheld should be integrated into an IP65 housing with the GPS and GSM antennas inside.
 
This equipment should be carried on the operator's back possibly inside a rucksack.
 
  • Second scenario
GPS receiver, GSM phone, their antennas and power supply integrated inside an IP65 box and attached to the handheld for ease of handling.
 
 
  • Third scenario
GPS receiver and antenna integrated inside the handheld PC.
 
 
Docking Station with GSM phone, antenna and power supply installed in car, truck or fixed base.
