Frequently Asked Questions
Q: How do I connect a Bad Elf receiver to my phone or tablet?
A:Pair the receiver via Bluetooth. On iOS devices, Bad Elf GNSS receivers use their MFi certification to automatically take over all location services. On Android devices, the same functionality is available by enabling mock location through the Bad Elf Flex App.
Q: Do I need corrections for sub-meter or centimeter accuracy?
A: With the Bad Elf Flex you do NOT need corrections for sub-meter accuracy, the device gets 30-60cm with just a clear view of the sky.
Q: What if I work in a remote area with no cellular service for RTK?
A: Use the
Base/Rover Kit
to set up a private radio link between a base and a rover. This allows you to achieve ~1 cm accuracy without relying on a cellular network.
Q: What affects the quality of my GNSS positions in the field?
A: Whenever possible, work in areas with an open sky view. Accuracy can degrade near tall buildings, dense tree canopy, or power lines due to multipath interference. The helical antenna on the Bad Elf Flex helps reduce these effects, and using RTK corrections further improves resilience in challenging environments.
Q: How accurate are elevations?
A: Vertical error is typically about 1.5× horizontal accuracy.
For more information about vertical accuracy here are some suggested articles
Q: Can I use the same receiver for both mapping and survey work?
A: Yes. The Bad Elf Flex Mini Extreme can serve as a compact mapping unit with SBAS or as a centimeter-grade receiver when used with RTK.
For heavier survey workflows or when you need better multipath mitigation, use the Bad Elf Flex.
Q: Do the devices have screens for field visibility?
A: Yes. Both the Bad Elf Flex Mini and the Bad Elf Flex have on-device screens that display key status information such as satellites, fix type, and corrections.
