SAC and Local Partner Balkantel, Complete Turn-key NDB Project for BULATSA

With local partner Balkantel, SAC completes a turn-key NDB Project for the Bulgarian Civil Aviation Authority BULATSA.

The turnkey project included the removal of existing outdated equipment and replacement with our 125 Watt Transmitters, PC1000/C4 Antenna Tuning Units, and Remote Control Units.

In 2020, Southern Avionics was awarded a procurement for a quantity of six SE125 Dual IP NDBs by BULATSA but the Covid-19 pandemic began in the midst of this project so implementation was delayed.

We had to work very closely and carefully with BULATSA, and our partner Balkantel to coordinate and handle the deliveries, SAT, re-installation, installations, flight checks, and, site acceptance tests and commissioning.

The Balkantel Sites are noted as: BOZ, DWN, GNA, KMN, WAK.

We are providing an extended warranty and look forward to working with BULATSA for their future requirements.

Our partner for this job, Balkantel Ltd of Sofia, Bulgaria, and Mr. Nikola Dourchev Commercial Director have proven to be an excellent and highly skilled company to be associated with.

Balkantel Ltd. is a project-oriented engineering company, established in 1990 and specializes in systems for management and control of air navigation, applicable in the civil and military aviation, specialized military communication and navigation systems, railway signaling systems, and safety and security systems for railways, air-forces, civil aviation, and energy sectors.

The SE Series NDB Transmitter uses state-of-the-art technology including powerful Renesas© Microcontrollers and Analog Devices© Direct Digital Synthesizers to provide accurate beacon signals in power levels ranging from 10 Watts to 125 Watts carrier power.

The SE unit provides simplified set-up & maintenance procedures, comprehensive BITE, and full Ethernet capability accessible by both internal and external RJ45 connections. 

The SE125 comes with built-in WebWatch software. WebWatch enables the user to control and monitor the transmitter on a laptop or PC. DHCP provides or the user enters an IP address to access WebWatch using any Ethernet/Internet connection.

Antenna Tuning Units (ATU) are used as a coupling between the transmitter and antenna.  An ATU is required to achieve and maintain proper tuning for the antenna and is used on all NDB and DGPS systems.

The PC-1000C4 Antenna Coupler is designed to match 200 - 1500pF / 2 - 25 Ohms antenna load in the 190 - 650 kHz frequency range, RF input power is 200 Watts continuous, 500 Watts peak.

The RRC 7700 is the latest generation of VoIP-based remote radio control.
