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-

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. Bottom photo shows the
interior of the seismic signal acquisition/control truck.
