Balance Price vs. Performance


How would you define the perfect GPS?

The perfect GPS has absolute accuracy and is free!

Is near perfect accuracy essential, without compromise?

When you need 1-cm accuracy, compromise is not an option. You will have to pay the price for complex GNSS hardware. Add a correction service and you have a very costly solution.

Dealing with a low-budget or no-budget circumstance?

If you already own a smartphone, you most likely have a built-in GPS receiver at no additional charge. However, that cellular-assisted GPS is not likely to provide consistently better than 5m accuracy. Sometimes that is acceptable, but rarely for GIS/mapping scenarios.

Do you need to assess tradeoffs between budget and accuracy?


The plot below shows a story that is clear. High accuracy is costly. Technology has advanced and GNSS devices are becoming more powerful and capable. Bad Elf devices are positioned well to provide mapping grade accuracy at an affordable price. If high precision is either too expensive or not really required, Bad Elf has your solution
