Valec Taps Into The Power Of Satellite Communications Provided By Globalsat Group And Inmarsat To Connect Brazil From North To South

Valec is a Brazilian railway construction and operation company with 550 employees. The public company manages three railways: the North-South Railway, the West-East Integration Railway and the Centre-West Integration Railway.

The organisation plays a major role in developing infrastructure across a very large territory with far-flung cities and complex geography, and is linked to the Brazilian Ministry of Transport.

Challenge:

Valec is currently in the process of building and operating the North-South Railway, which will run from Belém in the North to the southernmost city in Brazil, Río Grande, enabling the movement of valuable commodities. 1575 km of this railway is already in operation, but Valec is still building round 700km of the track. A Central Operations facility coordinates work across the entire span of the railway, controlling the movement of goods trains and other rail vehicles, ensuring that all building and engineering tasks run according to plan. Meanwhile, mechanics, engineers, builders, and other workers are all posted at different points down the length of the track to do construction work and maintenance on specific sections of the railway. Numerous maintenance vehicles drive up and down the line, managing the railway, delivering vital raw materials and moving workers.

Considering the sheer distances involved and the scale of the work at hand, communication between their vehicles, trains and Central Operations is key. Despite this, Valec’s communications previously relied almost completely on a paper system, whereby drivers would be given a ‘license’ from Central Operations, which would specify a beginning and end point for their journey and cargo.

This system was problematic on several levels – for one thing, it did not allow the Central Operations facility to have any real feedback on what its vehicles were doing. It also restricted the agility of Valec

rather than being able to react flexibly to changing events happening along the line and being able to adjust resource allocation accordingly by communicating with drivers, it instead left them with only one reliable point of contact – the paper-based system. Moreover, not being able to see where drivers were in real time represented a safety and health issue, as these drivers were travelling very long distances to remote locations on a daily basis. There was also an economic cost involved with trains – which can be up to 1km long – more likely to consume the extra 800 litres of diesel it takes them to stop and re-start to accommodate unanticipated events on the line.

Solution:

Seeking a better way of working, Valec opened an RFP process, in line with Brazilian federal government procurement regulations. Globalsat Group, a provider of satellite communications and equipment, submitted a proposal combining its technical deployment and management knowhow with the reach and reliability of Inmarsat’s satellite constellation and ground network, at the lowest price provided by any supplier in the process. Inmarsat’s fleet of multiple geostationary satellites delivers seamless global coverage, and this hybrid solution leverages this industry leading network in several ways:

  • GPS tracking constantly transmits the rail vehicles locations back to Central Operations.
  • Drivers are also equipped with push-to- talk (PTT) handsets, enabling them to communicate with Central Operations regardless of where they are.

Both of these functions are enabled by BGAN terminals integrated into the vehicles by Globalsat Group through its affiliate Globalsat do Brasil, and connected to the highly reliable Inmarsat L-band network, which during initial testing proved to have more than 99% availability even on a moving vehicle.

Benefits:

Valec now operates a sophisticated traffic control system, based on the known position of maintenance vehicles and commercial trains. The capacity to see exactly where the vehicles are at any given time and to reliably communicate with drivers throughout the track has not only helped Valec to work more efficiently, but also much more safely. Bruno Fontoura, from Valec Operations, commented on the hybrid solution: “The North-South Railway is a huge infrastructure project which will help drive our national economy. As a public company that acts for the wider social and economic good of Brazil, the railway must be completed on time and at the right cost, so we must use the right suppliers. Globalsat Group and Inmarsat met our needs very well – although the original project only involved PTT handsets, after we had begun putting in place the solution, it became clear that we needed the vehicles’ precise location to appear on our control panels. The two organisations adapted the solution to our requirements, and adjusted the hybrid solution to include the GPS tracking element that would prove to be such a vital part of the finished service.” “Importantly, the hybrid solution was skillfully integrated into our existing systems, meaning that we didn’t have to make any major adjustments to control panels or in Central Operations facilities to ensure the whole thing functioned. And finally, all this was delivered on time and at the lowest cost that was offered to us during the RFB process. The system works reliably, saving us money and improving safety standards, and has become the bedrock of the North-South Railway project.” Executive summary of solutions provided by Globalsat Group and Inmarsat:

  • Systems demonstrations, integration and testing.
  • Car kits containing a PTT device (Combox v2) and the satellite terminal (BGAN Explorer 325 BDU and antenna), for reliable hybrid communications.
  • Inmarsat high availability L-band service and redundant ground network.
  • GPS tracking for 15 maintenance trucks and for 4 commercial cargo maintenance trains.
  • Push to talk services for the 15 maintenance trucks and the 4 commercial cargo trains.
  • Globalsat Group PTT communications server located in a secure facility directly connected to the Inmarsat ground network.
