TGOR, the solution from Tecnobit – Grupo Oesía for Spain to achieve sovereignty in tactical radio communication

If the crisis caused by the pandemic has taught us anything, we need to undertake a process of reindustrialization to reduce our dependence on third parties. Just as no one considers the need to send our military aircraft, ships or main battle tanks from Spain for changes, updates or maintenance, neither should our country consider a prisoner of a foreign one, given the possibilities offered by technology Radio manufacturer to be offer. SDR (Software Defined Radio) offers.

So far, Spain is one of the few countries around it that lacks national sovereignty in tactical radio communications, apart from mere distributors or integrators of foreign products. When Tecnobit Grupo Oesa discovered this gap in national technological capabilities, it decided to expand its tactical communications division (which already offers tactical connections, encryption and audio management systems) by a 100 percent national radio, TGOR (Tecnobit Oesa Radio Group) to expand.

Tecnobit’s TGOR radio proposal is postulated as a purely national solution to the decision of the Spanish Ministry of Defense to renew its radio network for land, air and sea combat through the start of the SCRT (Joint System of Radio Tactics) program. This represents a growth opportunity for the Spanish defense industry that only exists every twenty to thirty years. The SCRT offers Spanish companies the opportunity not to sub-contract to large foreign industrial groups that have had a monopoly on C4ISR systems in Spain over the past few decades.

TGOR is a family of tactical radios defined by the TecnobitGrupo Oesa software and available in handheld, manpack, vehicle and air versions. They respond to the new digitization requirements of our armies (land, sea and air) during their operations. It is capable of providing the armed forces with superiority in the electromagnetic spectrum to address new tactical communication scenarios that require greater bandwidth and resistance to electronic warfare attacks and attempts to intercept the communication.

It guarantees the sovereignty of tactical communication by providing complete control over five essential areas: waveforms, both national and NATO / coalition, security elements (TRANSEC, COMSEC and NETSEC), the SDR platform including its communication software architecture. SCA / ESSOR standard, radio planning and configuration applications as well as manufacturing, development and maintenance at all levels.

The anti-access and area denial (A2 / AD) functions of the opponents have C4ISR systems as one of their main goals. Incidents of EW attacks (Electronic Warfare) in operational areas are increasing, and opposing forces are trying to intercept, locate and disrupt communications. On the other hand, the increasing sensorization of the battlefield to increase situational awareness and the survival of units (in combatants, vehicles, RPAS, etc.) with the resulting increase in data exchange makes it necessary to expand the available bandwidth.

21st Century Capabilities

TGOR responds to the needs of the 21st century fighter. The distinguishing features compared to other competitors are cognitive radio capabilities, dynamic frequency allocation, multi-channel reception, a bandwidth of 100 Mbit / s, the MANET IP network with more than 1,000 nodes and a national cryptographic module based on the technology of CIFPECOM.

As a cognitive radio, it adds an additional layer of intelligence to conventional SDR. Thanks to this, it can change its transmission and reception parameters, such as power, frequency, as well as modulation and coding schemes, depending on the needs of the user and the radio-electrical environment in which it works, thus adapting to the changing environment of the specialty operation. Battle. Spectral mobility is a more efficient electronic protective / countermeasure (EPM / ECCM) measure than mere frequency hopping to increase the low probability of detection and interception as the cognitive can anticipate the jammer and shift the transmission band before communication is compromised .

In an area of ​​application whose operation is located in non-radio controlled areas, the ability to use dynamic frequency allocation is a guarantee of the reliability of the communication. With its cognitive radio capabilities and dynamic mapping, it adapts to interference and spectral gaps.

Each TGOR acts as a spectrum analyzer. It collects information about the electromagnetic, analyzes it and consequently optimizes its use, detects spectral gaps, detects the hostile activity of jammers and counteracts this appropriately. This gives its communications a high level of survivability in electronic warfare environments.

Similarly, field deployments take place in unknown, unpredictable, changing, and potentially hostile environments where interference and connectivity issues arise. To the dense occupation of the spectrum and the rapidity of the movements of the units, the inclusion of new units that were not considered in the original planning and outside their natural sphere of influence, etc., we must add the hostile action to try to intercept and communicate to disturb.

The above problem can be addressed using its cognitive radio capabilities and dynamic spectrum allocation. Another differentiator is multi-frequency channel reception, which allows you to receive and interpret multiple frequencies simultaneously with a single RF header. This leads to an increase in the performance of the receive rate, much lower latencies, a higher speed at the merging of nodes and the formation of a single flat network with a larger number of users whose subscribers can reach more than 1,000.

The multi-channel reception capacity enables a linear relationship to be maintained between the number of network members (size) and their allocated communication resources (spectrum). The ability to manage extensive frequency resources gives TGOR a clear advantage in dealing with increased network traffic, which is reflected in scalability. When used, more radios can join without affecting performance.

As a multiband radio, it can be operated in VHF, UHF and L bands and can be expanded up to the S band. Depending on the form factor, it can contain up to 3 RF headers, so you can have up to 3 independent channels. The waveform library contains wide and narrow band MANETs for air-to-air and air-to-ground communications. It also includes NATO waveforms and a gateway that guarantees interoperability with those of radios.

It enables the radio medium to be used as an ad hoc cellular network (MANET) so that each of the nodes (aircraft, vehicles, foot fighters, sensors, effectors, etc.) can communicate with one another via on-demand networks. without an existing communication infrastructure. It also has a waveform development kit, a tool that allows the user to run it autonomously with software and / or firmware depending on the specific needs of the waveform.

Technological sovereignty

In other words, these tools allow Spain to develop national waveforms that run on the SDR TGOR platform. With this in mind, radios can host the users sovereign waveforms like ESSOR HDR WF, ESSOR NBWF, ESSOR 3DWF and ESSOR UHF SAT WF, as well as NATO / Coalicin standard shapes like Saturn, NATO NBWF, COALWNW etc. This ensures the interoperability of the HF at NATO level. With TGOR, the armed forces can develop and install their own waveform applications.

It is equipped with a nationally developed cryptographic subsystem based on the COMSEC CIFPECOM module. External encryptors are also supported. This ensures cryptographic interoperability at NATO level. Therefore, TGOR radios are equipped with an internal or external cryptography module that is nationally owned. The cryptographic subsystem enables national control over the cryptographic processes that support the operation of the radio. This is a fact that enables the equipment to be accredited for the transmission of national classified information.

It offers full capacity for the configuration and management of wireless networks and facilitates their integration into the users’ communication managers as well as their optimal configuration for the transmission of information from command and control systems such as BMS, TALOS and AMPS.

Tecnobit’s extensive experience in tactical communications along with a solid industrial plan based on a supply chain of Spanish companies will allow Spain to give Spain the ability to design, update and develop, maintain and develop throughout its lifecycle manufacture tactical radios. Hence, this proposal differs from others because of the mere manufacture and assembly of third-party products.

TGOR is more than a single corporate project. It is designed as a tractor project for the Spanish defense industry. The impact on the entire defense industrial base will be remarkable. Contributing to the revitalization of the sector, promoting a new industrial model and developing a dual use of technologies with radio communication applications for critical infrastructures and civil protection.
