The Solution Rating System
|
|
| With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating. - The Grade of the Solution
- The Zone Rank of the Expert Providing the Solution
- The Number of Author and Expert Comments
- The Number of Experts Contributing
- The Feedback of the Community
Your Input Matters Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site. If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Asked by aemekli in GIS & GPS Programming
Hello,
I know that a GPS device must connect at least 3 satellites to find a location on the earth. But can we tell a GPS device which satellites to connect. For example: I want my GPS device to connect only the 3., 5. and 8. satellites.
More Information : Why do I need this?

What we need mainly is to locate the position of several vehicles in a restricted outdoor area (a local outdoor area) precisely (with max. 1 meter tolerance). And GPS devices can be influenced by environment conditions and weather. Since the the vehicles, which we want to trace, are in a restricted area, we know the GPS location of that area. What we think is to use a gps device in each vehicle and another gps device whose location is static and whose precise GPS location is known. In this case, even if the GPS information is different from what it has to be, we get the difference between them and correct the other GPS devices' (the ones on the vehicles) information. But each device connecting different set of satellites would result different inaccurate GPS information. Thus we cannot correct those values by referencing the GPS whose location is static.
Could anyone please help?
Thanks,
Afsar.
