GURU - radio transmission system


Anyone interested in aviation has heard at least once about services that enable real-time tracking of aircraft in the airspace. Unfortunately, what has long been possible for use in airplanes and helicopters thanks to devices called transponders, was only a vision for parachutes and paragliders. However, if such supervision were possible, would it not improve security? Until now, the problem has been that not everything can be seen. And there are many problems... Landing in an adventitious terrain a few kilometers from the airport can provide good fitness training if we want to return to it. It also happens that we land in a place where the GSM network coverage is limited. What is worse, there are landings in the forest and even then climbing down the tree can be a big risk. If only someone at the airport knew we had a problem, he could help ...

We are pleased to present the GURU system, which already allows you to provide advanced, previously unavailable flight data. Composed of two subsystems: data transmission and video transmission, it will allow the deepening of the instructor's situational awareness and, consequently, to develop recommendations that can be sent to the pilot even with the use of a traditional radio station used in aviation.

 

 

A handful of facts about GURU?

Verbal communication is the primary form of communication at an airport, however, it is limited to how loud we can shout. It is impossible to emit a voice for a distance of a few kilometers, and yet at this distance, there are often jumpers from the flight origin. There is nothing easier to solve this problem... It is enough to use the aviation radio, set a common frequency, and communicate with its use. However, practice shows that even though voice communication is possible, what we have to say on the radio becomes a problem. If we are to make rational decisions, they must result from good situational awareness. From the airport level, we have a sense of sight. We can see what someone is doing and react on that basis. The situation is not, however, simple. Observing what is happening in the air can be difficult: it is difficult to locate the jumper in the sky, and eagle vision is required to determine what he is doing. With this in mind, we have designed the GURU module, which includes:

  • data transmission module,
  • video transmission module.
  • They can be used as a combined data source for the GUIDE Instructor Stations or individually.

    What is special about our data module? After all, a wireless network works in every home and high transmission speeds are available. However, additional questions should be asked.

  • Will we be able to connect to the home Wi-Fi network from a few kilometers?
  • Does the GSM network work when we're flying?
  • Are we aware of the maximum transmission power permitted by law?

  • It is the transmission power, mainly in combination with the selected transmission frequency, that determines the maximum range to be obtained. In our solution, we focused on making our system work well in airport conditions and enabling the acquisition of data on parachute jumps and paragliding flights that were previously unavailable. With this in mind, we developed a terrestrial segment of the transmission system based on an omnidirectional antenna, which in the tests carried out showed the possibility of data transmission up to 30 km. Moreover, it enables:
  • data visualization in GUIDE along with automatic warnings about dangerous flight conditions,
  • simultaneous supervision of a group of up to 10 jumpers equipped with GUARDA-TE recorders,
  • preview of the position, altitude and direction of flight on the map,
  • transfer of advanced flight parameters (descent speed, spatial orientation angles, ground speed).
  • Do you think that what you see from the ground and in the instructor's station is not enough for communication? Sometimes this may be the case… For example, when you want to see an image from the air in real time. We have designed a video transmission system with this in mind. The GURU-VIS module will allow you to connect to any Android device that will serve you as a source of camera data. It can also be AR goggles. However, the challenge is obtaining transmission ranges that allow the reception of this data from a long distance.

During the project implementation, we confirmed the possibility of video transmission with a range of up to 5 km.

    We recognize that the ability to transport items can be critical to acquiring equipment. For this reason, we have worked to ensure that the use of our system is trouble-free. First, we focused on making the transmission parameters as good as possible. What would the transmission system be if it could not communicate? But the other factor taken into account was the ability for you to use the system in operational conditions with just a few minutes needed for preparation. Hence the use of tripods, which allow for quick transport, but also improve the conditions of radio wave propagation for the antennas used. Another aspect was the ability to apply the system even in small centers. We are aware that few of them can afford to buy a transport car for the sole purpose of transporting the antenna... and therefore our solution is characterized by small dimensions and mobility. You can easily transport the transmission system in an ordinary car. There is something else we are proud of. Our transmission modules have battery power and Wi-Fi modems. Thanks to this, you will place the antenna where it is best for good transmission ranges allowing you to communicate with parachuters (e.g. away from the hangar), and during this time you will supervise the flight using GUIDE from a shaded or air-conditioned room.

    Our transmission system has been designed as a part of the PSSP-01 project, being a link between elements of the air segment (GUARDA-TE recorders) and elements of the ground segment (GUIDE instructor station), which will enable ongoing supervision over air operations. Thanks to it, at any time, having a GUIDE instructor station and GUARDA-TE recorders, you will gain the possibility of ongoing flight supervision, and in the case of using the version with video transmission, a mid-air view from camera.

    The transmission system was entirely designed and manufactured by us. Are you thinking of an alternative use? Do you want to monitor the work of other flying objects? Do you need to expand the system to a larger group of users? Or maybe you are interested in adapting the system to a different frequency? Contact us and we will try to help you. We offer individual orders:

  • development of data transmission devices,
  • designing dedicated transmission protocols,
  • estimating the budget for the radio transmission link,
  • testing of radio transmission systems.
