The HG-RE04 is a satellite navigation development platform that offers combined GPS/BeiDou positioning, source code for the correlator (HG-CORR V1.3) and DSP processor (HG-DSPGPS V1.3), and a complete hardware design based on a TMS320C6747 DSP and EP4CE115 FPGA. It includes a 1U aluminum chassis, internal battery, and multiple interfaces such as JTAG, USB, serial ports, and RF connectors.
The platform supplies power via 220 V, USB, or an internal 5000 mAh battery, provides a +5 V/2 A supply for the receiver, and supports the MAX2769 GPS RF chip. Technical performance includes cold‑start under 45 s, hot‑start under 8 s, horizontal accuracy of 10 m CEP, vertical accuracy of 15 m CEP, and speed accuracy of 0.2 m/s. Documentation includes hardware schematics, software specifications, test software, and a packing list. This manual is written in Chinese.
