Delta TRE-3 QZSS LEX released

We announce the release of Delta TRE-3 QZSS LEX receivers. It is capable to receive not only LEX pilot, but LEX data signal too.

Delta TRE-3 According to Japan's space agency JAXA, "LEX (L-band experiment) is a unique signal from QZSS satellite. The objectives of LEX signal are to enhance the performance of GPS(realizing improved precision) and to establish the next generation's positioning based technology". Unlike other known GNSS signals with biphase keying, LEX uses code shift keying instead. This method required more efforts to receive the data, but has higher bit rate under the same C/N0. Current LEX data stream is 2000 bits per second, which is significantly higher than for other signals.
