[OLPC-Games] Provide GPS positioning: Low Cost 1M to CM Level Accuracy

[heixinr at tom.com]

Dear project owners:

  Our company has been working on GPS solutions which can position & track targets
in real-time mode with high accuracy. Our works provide three basic advantages:

1.self service & real time service

  Users can track targets from his/her own computer instead of remotely from any 
other charge based on-time service. Users position targets in real time and without 
any delay; in another word, the data is processed in real time.

2.high accuracy

  No more 10 meters plus tolerance! With our technology, you can manage the accuracy 
from submeter level to even centimeter level.
 
3.low cost for your shrinked budget

How does it work?

  a. We use 1 GPS receiver as reference station which is permanently static and positioned;
  b. Reference station creates corrective information to other GPS receivers;
  c. the computer displays corrected position information;
  d. We have important algorithms which help to create corrective information;
  e. The communication are wireless among tracked targets, reference station and computer:

     e-1 Wi-Fi: 0-100 meters 
     e-2 GPRS: within cellular phone network 
     e-3 RF: 100-1000 meters
     e-4 Data link device: up to 50-60km

Some applicable areas of high accuracy GPS are:

  Agriculture
  Logistics & Transportation
  Vehicle Control
  Outdoor Automation & Robots
  Land survey, Pipeline & Navigation Marks
