Since 1992 the company RETRA (earlier – Engineering Bureau of the Radio Electronics) has been developing and manufacturing electronics. The company RETRA develops and produces radioelectronics and engineering documentation at customer’s request, as well as at its own discretion, providing the guarantee and post-guarantee support. The product range includes about 100 products.
The focus area of the Company is electronics for the automobile transport and transport infrastructure:
The majority of products are manufactured using the contemporary hardware components and advanced technologies.
At the present time 35 highly-qualified specialists work in our company: electronics engineers, programmers, radio adjusters, assembly fitters, radio electronics controllers, turners, milling machine operators. The company has the diploma of the 3rd specialized exhibition ‘Passenger: transport, terminals, services”, held in Moscow in the All-Russian Exhibition Centre in 2004. Diploma was awarded for the development of devices and voice announcement systems for the automobile transport.
The company has the diploma awarded by the expert board of the exhibitions “The Best in Russia”, “The Best in Moscow”, “The Best in the Moscow Region”. One of the biggest projects, performed by the company exclusively, is the automatic system of the dispatcher’s control of the urban public transport in Nizhniy Novgorod, which allows to monitor and control the traffic of the passenger buses of the municipal enterprise “Nizhegorodpassajiravtotrans” and mini private buses of the central dispatch service of the municipal enterprise of Nizhniy Novgorod. Within the framework of the project more than 2 thousand passenger buses of different types were equipped with these automatic systems. The computing system of the central dispatcher service was created on the territory of the municipal enterprise Nizhegorodpassajiravtotrans. The relevant software was developed, which allowed to process more than 100 thousand marks from the buses every 24 hours and to get more than 30 various information statements about the bus route. The automatic voice announcement systems are delivered to the automobile factory Nefaz, where they are mounted into the series-produced buses. The company has a number of patents and utility models.
OOO RETRA is open for the cooperation, we will be especially interested to collaborate with the electronic, engineering and automobile factories.
