ALTI UAV Ground Control Station

When we look at the sky and we see airplanes flying over our houses, some of us think that those metal birds are being flown by pilots seating in their cockpit reading charts, communicating with air traffic controllers, or even drinking coffee. In today’s world, the way airplanes are being flown is changing, and one of those changes is that now we count with Unmanned Air Vehicles (UAV). UAVs as its name indicates, does not count with a pilot in the cockpit but with a ground control station were the decisions made by remote pilots affect positively or negatively how the UAV will perform or behave. The ground control station of UAVs varies depending on the characteristics and use of the vehicle, some more complex than others.

ALTI, one of the world leaders in unmanned vertical take-off and land (VTOL) aircraft manufacturers and developer company, has among its fleet of UAVs the ALTI Transition. The ALTI Transition counts with a Ground Control Station (GCS) unique in its type. It is a complete control and command station as well as a stand-alone aircraft control camera gimbal and sensor control unit (ALTI, n.d.). 


The frame and power life

The GCS is housed by a lightweight pelican ‘air’ case that includes a high-quality intel computer, relevant mission planning, and operation software (ALTI, n.d.). These features are very convenient for the transportation of the GCS as well as for the maneuvering and control of the ALTI Transition UAV. Two of the biggest advantages of the ALTI GCS is that it can be set up with multiple power options including hot swappable batteries. The result, the operations can last for extended periods of time.

Long Range Data and Video

ALTI GCS counts with advanced long-range aircraft data telemetry and video link, as well as Multiple Input Multiple Output (MIMO) technology which includes (ALTI, n.d.):

·         High quality Intel NUC computer

·         Dual screen design layout

·         15.6” LED HD display monitors (allows for 160°/160° viewing angles)

·         Digital and video link powered by Microhard MIMO 2.4Ghz pMDDL2450 ENC radio systems

·         Up to 62 miles of long-range data and video features

·         Backup data telemetry link

·         Long range control link

·         Main digital data link (flight planning and telemetry)

·         MicroHard radio modem system

·         Encryption

·         Control links

·         Any payload/HD video software the client has opted to use with ranges of up to 70km



Communication between the GCS and the UAV is essential for the success of the mission carried.  Communication is maintained thanks to a radio controller for aircraft control, power packs, antennas, and all extras and accessories (ALTI, n.d.). 

Long Range and Control Link

According to ALTI’s official website, “ALTI GCS counts with a long-range low frequency C2 control link for full time LOS control and override of the aircraft.” This means that the command and control of the UAV can be well handled from long distances without being interrupted by environmental changes.

Visual Display

ALTI GCS counts with a high-quality intel computer with dual HD display (ALTI, n.d.). This is of great help for remote pilots/operators because it will be displaying better images with details of where the UAV is located. The visual display can help on the decision making of the mission carried. The GCA is also loaded with mission planning, payload, and control software that helps the UAV to be ready to fly at any moment (ALTI, n.d.).

As a result of ALTI giving its costumers the option to select their prefer software, it could be recommended to use the Visionair GCS software from UAV Navigation, a company specialized in the design of flight control solutions. Visionair is perfect for the planning and execution of UAV missions, specially because it is compatible with fixed wing UAV like it is the case of the the ALTI Transition UAV. Some of its feature includes (UAV Navigation, n.d.):

·         Mission-oriented interface.

·         Fully featured UAV mission planning and execution application, with GUI.

·         Platform: PC/laptop (with keyboard + mouse).

·         Suitable for fixed-wing, helicopter or multi-rotor UAVs and targets.

·         Main Flight Modes: Auto, Manual, Fly-To, Hold (Hover), Safe (Return To Base).

·         Fully Auto Take-Off.

·         Fully Auto Landing.

·         Camera Control Modes: Air, Ground, Geo, Pilot View, Stow, Rate (with integrated video display).

·         Waypoints: 100 max.

·         Range: Unlimited.

·         Altitude: Unlimited.

·         Full DEM support.

·         Link Quality panel.

·         Target Editor.

·         Fly/No-fly Zones.

·         Rulers.

·         Full range of configurable alarms.

·         Compatible with all kinds of digital mapping.



Determining the right hardware for a GCS depends on the physical requirements the UAV will be subject to and the computing requirements the GCS needs to provide in order to collect accurate data. The following charts presens different GCS options to take into consideration when purchasing a hardware. 



Small UAVs GCS can be subject to be stolen, lost, or damaged. A possible solution to this as well as for the rugged hand-held controllers is to take advantage of the new era of automation. Taking some of the control functions from the GCS and providing the UAS with more autonomy could be a good solutions (Nace, 2013).
