Project Breadcrumb: Tackling Problems from GPS Loss in UAVs

Posted by Betsy Lillian on March 12, 2015 No Comments

PrecisionHawk and the University of Toronto have announced a collaboration to develop a solution for unmanned aerial vehicles (UAVs) in the event of GPS loss or jam.

Called ‘Project Breadcrumb,’ the partnership will facilitate safe UAV travel even when all other communications or navigation systems are lost. The objective is to integrate the solution directly into PrecisionHawk's low altitude tracking and avoidance system (LATAS) for use on any UAV platform.

“As we work to mitigate the risk of operating small UAVs in the national airspace, one of the key concerns comes from the possibility of losing GPS signal or GPS interference,” says Ernest Earon, president and co-founder of PrecisionHawk.

“The University of Toronto has an excellent research history in navigation and control in GPS-denied environments, like space, where technology needs to know where it is and where it needs to go without a GPS signal,” Earon explains.

In partnership with PrecisionHawk’s engineering team, Project Breadcrumb will be developed in two phases by University of Toronto researchers and their students at the Institute for Aerospace Studies.

The collective is welcoming conversations and feedback from regulators, airspace safety inspectors and members of the Civil Aviation Authority.

PrecisionHawk, a member of the Small UAV Coalition, is a UAV and remote sensing company operating out of Indianapolis; Raleigh, N.C.; and Toronto, Ontario. LATAS, first introduced by the company in January, was developed to provide drone flight planning, tracking and avoidance using real-time flight data transmission based on worldwide cellular networks.
