Aces/geophones FOR A TECHNOLOGY THAT MEASURES millimetres and nanoseconds, it might seem counterintuitive that GNSS can support cutting-edge science on the planetary—and even interplanetary—scale. But with the aid of two types of NovAtel antenna designs, that is happening today. After all, a GNSS receiver is helpless without the antenna element that pulls satellite signals into its digital processing channels. The Atomic Clock Ensemble in Space (ACES), a payload destined for installation on the International Space Station (ISS), will use two exceptionally accurate clocks along with GNSS receivers coupled with a NovAtel antenna for a variety of experi- At left: Top three photos show images from a seismic survey looking for oil deposits near Las Choapas, Mexico. The survey used special geophones that incorporate a NovAtel dual-antenna design to help capture the location and shapes of subterranean formations.
