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 functions. For a complete list of
available options and details, visit the TPS website or consult your
TPS dealer.
• Type of signal (standard GPS L1; optional GLONASS L1)
• RTCM Input/Output (standard)
• Advanced multipath reduction (standard)
• Wide Area Augmentation System (WAAS) (standard)
