Arrow 100® Submeter GNSS Receiver

Submeter GNSS Accuracy Worldwide with Arrow 100® and Arrow 100+™

Real-time Submeter GNSS Receiver Worldwide

The Arrow 100® is a submeter, multi-constellation GNSS receiver designed to be used with any iOS®, Android, or Windows device. When GPS satellites are just not enough, the Arrow 100® connects to GLONASS, Galileo, and BeiDou signals — creating access to at least 100 satellites! This uniquely designed GNSS receiver squeezes more accuracy from free SBAS corrections than any other receiver in the world. With its use of patented technology, the Arrow 100® delivers superior accuracy and performance under trees, around buildings, and in rugged terrain. Accurate positioning occurs in real time, with no post-processing required. The Arrow 100® was designed specifically with GIS users in mind.

How to Get Free GPS Sub-Meter Corrections with SBAS Satellite Systems GPS GIS Mapping

What is SBAS?

SBAS stands for Satellite Based Augmentation System.  An SBAS provides a free source of corrections to augment GNSS (positioning) signals. SBAS are usually developed with the investment of a government, a government department, or groups of governments, such as the European Union. An SBAS-compatible GNSS receiver, such as the Arrow 100®, receives and processes these free submeter differential corrections in real time, resulting in live submeter positioning with no post-processing required. The Arrow 100® supports all worldwide SBAS, including WAAS in North and Central America, EGNOS in Europe and northern Africa, GAGAN in India, MSAS in Japan, and SouthPAN in Australia/New Zealand.

What Customers Say about the Arrow 100®

Tommy Shifflett

“Without the accuracy of the Arrow 100, it would not be possible to locate and harvest seeds from these plants at a time in summer when they would not normally be visible amongst the tall grass.”

Larry White

Volunteer Site Supervisor, The Nature Conservancy of Canada / BC, Canada

Larry White

“After updating several nearby cave locations with the Arrow 100 coordinates, I recompiled the overland survey and calculated an azimuth and distance from a cave that I thought should be close. This led right to the lost entrance!”

Tommy Shifflett

Co-Founder, Proyecto Espeleológico Sistema Huautla (PESH) / Oaxaca, Mexico

Dann Block

“We looked at all the equipment and software out there, and the Arrow 100 had the best ratings under trees. We determined that it was the best GNSS receiver available, with the best performance, that fit our budget.”

Dann Block

Lead Gardener, Woodland Park Zoo / WA, United States

Al Schaeffer

“I just bought an Arrow 100 and am very impressed with its accuracy right out of the box. The unit continues to operate flawlessly, giving me almost constant accuracy below 1 meter!”

Al Schaeffer

President, Northern Forests, LLC / ME, United States

“Two years ago, we went with the Arrow 100, and it’s much more accurate than the Garmin. Now, we are sure we will get back to the same tree — at the same exact spot”

Daniel Pilote

Forestry Technician, City of Montreal / QC, Canada

Håkan Bergstedt

“The Arrow 100 shows me time after time how extremely accurate the measurements were that they [the original boundary markers] have made.”
