Shulou(Shulou.com)11/24 Report--

CTOnews.com September 5 news, Liyang chip announced that the company has recently completed the world's first Beidou short message SoC chip test program development and entered the stage of mass production, the company exclusively provides wafer-level testing services for the chip.

Liyang chip said that this time, the company has successfully completed the research and development of the test scheme of Beidou short message SoC chip, which provides navigation satellite simulation signals, can simulate 3 BDS B1 satellites + 3 GPS L1C / A satellite signals (satellite signal strength-133dBm, dynamic scene speed is not higher than 2m / S), and can comprehensively test the RF and baseband functions of Beidou navigation chips with different functions. At the same time, it can meet the testing needs of civil global multi-mode and multi-frequency chips. The company tests the key parameters of the chip by simulating Beidou satellite signal, including signal reception, differential enhancement, integrated navigation function, AGNSS function, first positioning time, sensitivity, accuracy, multi-tone interference cancellation, power consumption, etc.; in addition, in the RF part, the chip's multi-frequency parallel reception, if I / Q output and ADC sampling performance are analyzed and evaluated.

CTOnews.com learned that at the end of July this year, the China Satellite Navigation system Management Office announced that China Arms Industry Corporation, China Mobile Communications Group Co., Ltd., China Electronic Technology Group Co., Ltd., and domestic mobile phone manufacturers have jointly completed the development of China's first mobile Beidou short message communication RF baseband integration chip (short message chip). The satellite communication capability of popular smart phone is realized.

The short message chip can be integrated into the smartphone, which is helpful to promote the short message function in the field of mass consumption. It is expected that the first batch of mobile phone products that support Beidou short message communication function will be put on the market in 2022. As one of the four major satellite navigation systems in the world, Beidou is the only satellite navigation system with short message communication function at present.

It is reported that the short message chip conquered a number of key core technologies, realized the "one number and two networks" design of mass mobile phones with "no card change, no number change, and no additional peripherals", and realized the satellite communication capability of mass smart phones for the first time, effectively solving the problem of "not in the service area".
