Option Authorization File (Oaf); Twin Antenna System (Hd2) - Topcon MR-2 Operator's Manual

Option Authorization File (OAF)

Topcon Positioning Systems issues an Option Authorization File (OAF) to enable the specific options that
customers purchase. An Option Authorization File allows customers to customize and configure the receiver
according to particular needs, thus only purchasing those options needed.
Typically, all receivers ship with a temporary OAF that allows it to be used for a predetermined period of time.
When the receiver is purchased, a new OAF permanently activates the desired, purchased options. Receiver
options remain intact when clearing the NVRAM or resetting the receiver.
The OAF enables the following kinds of functions:
•
Signal tracking (standard L1 GPS; optional L2, signal tracking)
•
Update rate (standard 1Hz; optional 5, 10, 20, 50, or 100 Hz)
•
RTK at 1, 5, 10, 20, 50, and 100 Hz
•
RTCM/CMR Input/Output
•
2-D attitude determination
•
Advanced multipath reduction
•
Satellite Based Augmentation System positioning (WAAS/EGNOS/MSAS)
•
RS-232C (2x) connectivity
Visit the TPS website (or consult a TPS dealer) for a complete list of available OAF options, details,
and upgrades.

Twin Antenna System (HD2)

The MR-2 receiver includes a twin antenna system called HD2. It derives 2D attitude parameters, namely the
heading and inclination, of the baseline between two antennas mounted on a platform. For more information,
