At 19: 21 on July 7, 2020, the first high-speed Internet airplane successfully made its first flight as the flight QW9771 of Qingdao Airlines landed safely at Chengdu Shuangliu International Airport, opening the digital mileage of new infrastructure construction of CAAC!
GRGTEST was responsible for all airworthiness certification tests and appraisals before the first flight of the airplane. At the same time, with the comprehensive service mode of "scientific research and design + system airworthiness test + whole-airplane on-site TPED test", GRGTEST participated in the analysis of EMC and reliability design before the installation of airborne satellite communication products, which can assist in the system networking and airworthiness certification (FAA + CAAC), and assist Qingdao Airlines, China Satcom and FTS to successfully make the first joint flight, providing testing technical support for the construction of the "high-speed Internet in the air + air-to-space integrated satellite networking"!
GRGTEST is once again to protect the safety of China's civil aviation after C919 and AG600!
How awesome is the first high-speed Internet airplane of China?
↓
The first air Internet aircraft
with independent intellectual property rights in China
has broken
the long-term monopoly situation of foreign manufacturers in this field.
The XstreamSAT system
is installed to
connect the first and the only one Ka band high-throughput satellite (ChinaSat No. 18) in China.
The bandwidth rate of the single airplane can reach 150Mbps.
It means that
even if you and your teammates are separated from each other,
you can still play the game
with four people
and become the winner smoothly
Security is undoubtedly the most important
for civil aviation
There are millions of components in large airliner,
thus the electromagnetic environment of airborne electronic equipment is complex.
It is necessary to carry out the strict inspection of the modified airplane
in order to ensure that the equipment on the airplane
without any interference
And GRG Test was also lucky
to have made a little bit of (glorious) contribution to it

(1) May 2019:
Entrusted by FTS (Beijing) Technologies Co., Ltd. (hereinafter referred to as FTS) and the Federal Aviation Administration (FAA) of the United States, GRG Test was responsible for the airworthiness certification test for DO-160G airborne satellite communication system. The company took advantage of national integrated management and control to deploy laboratory resources in Xi'an, Guangzhou and Shenzhen, so as to immediately establish the FAA airworthiness test project group, and set up the technical backbone team to prepare the test scheme for the full security.
(2) May - June 2019:
Overcoming the short test cycle, heavy tasks, verbal communication, technical difficulty and other problems, the technical team worked in three consecutive shifts in order to complete the designated DO-160 test (including electromagnetic and environmental tests) of the 4 component products of the system.
(3) December 2019:
The technical team conducted a T-PED test on the Airbus A320 airplane of Qingdao Airlines after the satellite communication system was modified at the Jinan Yaoqiang International Airport. Tests of the front door coupling and rear door coupling were carried out for the added WiFi system in accordance with the DO-363 standard and the requirements of FTS, covering systems tests of WiFi, GPS, HF, VHF, VOR, ILS. As there were no similar cases that can be used in China, the selection of test position, reasonable determination of the test frequency band, selection of sensitivity criteria and tailoring of test standards were all new challenges for the technology team of GRGTEST. At the same time, the test can only be carried out at night due to the control of the airport in the daytime. Strong wind, low temperature and continuous all-night work are all physical and psychological tests for testers.
According to the opinions of FAA airworthiness experts, as the technical team constantly adjusted the test parameters during the test, and assisted the crew to check the performance of airborne equipment, the external interconnection of all required test ports of the system was finally realized; all the results met the requirements of FAA and the task was successfully completed after continuous fighting in the whole night.
From "zero" to "integration",
many difficulties have been overcome
Standards were strictly observed
to protect the safety of "all corners" in the whole cabin
The professional performance of the GRG Test technology team
has also been recognized by customers
The commendatory letters from the customer
The roc flies up with the wind and soars into the sky for thousands of miles
GRGTEST will continue to
help the speeding-up of high-end equipment localization,
and play a technical support role in improving the quality
and efficiency of new civil aviation infrastructure
We wish China's civil aviation industry to have a higher, farther and broader future!
