Differential GPS

DGPS or Differential GPS is a system devised initially by the US Coast Guard, now international maritime standard which demands GPS signals be accurate to within 10 metres at all times.

It employs a fixed, land DGPS reference receiver to remove any errors from the triangulated GPS signals, then transmits the necessary correction factors to mobile GPS receivers in the area. DGPS does require an added beacon receiver to communicate with the standard GPS unit.

3D Printed Thermoelectric generators
Thermoelectric generators convert ambient heat into electrical power, providing a means to run sensor systems without relying on batteries, anywhere where there is a heat differential present. Unfortunately, until now it has never been possible to 3D print them, meaning their inclusion increased the cost of sensor systems, dictated design aspects, and prevented them from being manufactured in a single print run. None of these factors are entirely applicable any longer.
