Magellan, a world leader in GPS+SBAS technology, now offers the AC12 OEM board with raw GPS carrier
phase observables as a standard feature. Leveraging more than 15 years of OEM expertise in carrier phase
technology, the AC12 is capable of precise carrier phase output while remaining cost effective. For
high-precision applications constrained by cost and size, the AC12 board is the ultimate solution.
High-Accuracy Carrier Phase
The AC12 is a low-cost board with carrier phase measurements that deliver high-accuracy and flexibility
usually found only in more expensive GPS boards. The AC12’s extremely accurate carrier phase data can be
used for navigation and provides an advantage in a variety of applications, enabling users to apply their
choice of carrier smoothing algorithms to improve the pseudorange positioning accuracy and even perform
carrier-phase differential positioning.
Innovative Satelite Tracking Technology
The AC12 supports differential remote operation and is capable of tracking Satellite Based Augmentation
System (SBAS-WAAS/EGNOS/MSAS) satellites to enable enhanced and free-of-charge DGPS positioning.
Next-generation board design minimizes the impact of common mobile application challenges such as
skyward obstructions and GPS signal multipath, while superior signal reacquisition techniques ensure
position availability and reliability.
Low-Cost Solution
For many applications, such as agriculture, GIS and mapping, the AC12 provides high-performance GPS at a
fraction of the cost of “high-end” alternatives. A field-proven design built on Magellan's world-class GPS
engineering capabilities, the AC12 OEM board is also ideal for land and marine navigation, low-cost heading
and attitude systems, deformation monitoring, asset and people tracking, relative navigation, automotive,
military, and even golf course management - delivering reliable, consistent position and raw data including
carrier phase measurements under the toughest conditions.
