As examples, inertial navigation or laser or vision-based techniques (VSLAM etc.) might be ways to deal with GPS issues.
- hueving 12y agoMissiles used by the military already use inertial navigation to avoid GPS jamming issues so it's definitely possible.
- asynchronous13 12y agoit's definitely possible. but the price point for inertial sensors that are accurate enough to work without GPS is a lot higher than the price of the MEMS sensors that are currently used.
- robotresearcher 12y ago> it's definitely possible. You can't track an external, independently moving object using only inertial sensing.
- robotresearcher 12y agoHow does inertial navigation help with following people for a flying camera platform? Even if the subject carries a sensor, the reference frames will drift unbounded. Visual tracking should work, but is not reliable yet. Lots of people are working on it.
- jjwiseman 12y agoRight, I'm thinking of inertial navigation to help out in a case where you have spotty GPS and you lose it for 10 seconds. It's not practical for these sorts of applications to use only inertial nav, but it can help in the region between full GPS and no GPS.
