Thank you for purchasing RTAP2U, a high-precision GNSS receiver. This user guide is

designed to assist users in configuring the receiver and utilizing its features.

RTAP2U is the dual-frequency multi-band GNSS receiver that uses a u-blox ZED-F9P

module. It can receive GPS, GLONASS, BeiDou, Galileo, and QZSS signals. The

receiver supports GPS L1 C/A, L2C, GLONASS L1OF, L2OF, Galileo E1B/C, E5b,

BeiDou B1I, B2I, QZSS L1 C/A, L2C, SBAS L1 C/A signals and can process 184

channels. The device supports RTCM protocol and RTK, VRS, FKP, and PPP-RTK

positioning are available. PPP-RTK positioning based on SSR correction messages can

be enabled through a simple firmware update. With PPP-RTK, more reliable and

accurate navigation is achievable.

RTAP2U delivers centimeter-level accuracy within a few seconds at a data output up

to 20 Hz and provides an accuracy of about 2 centimeters. The device is lightweight

and hand-held size which allows users to carry it and use it for not only surveying but
