Government & Security Solutions

Often, they are hampered by interoperability problems, unstable communications infrastructure or intermittent signal issues.

[With 24/7 year-round global customer support,](/service-desk) AST Networks' managed services deliver end-to-end solutions designed specifically to maximise performance where and when you need it most. [Satellite communications terminals, modems and VSAT systems](/products?sector=10) can be used to set up temporary offices, with access to applications, head office communications or even video conferencing solutions.

Fully deployable satellite communications anywhere on the planet

Many ambulance crews across the globe operate in poor or non-existent radio/GSM coverage areas or suffer from blackspots which can interrupt coverage during potentially life-threatening situations. AST Networks can help provide robust, reliable communications on-the-move including [vehicular mounted satellite terminals](/products/explorer-8120-12m-stabilised-auto-acquire-drive-away-antenna-system) and [push-to-talk radios](/products/explorer-push-to-talk-ptt). 

Ambulance

Fire crews operating in remote areas of the world often must tackle wildfires which can be dangerous as they spread fast, change direction, jump to other areas, potentially threatening life. AST Networks' robust communications solutions for fire services include vehicular mounted satellite terminals and push-to-talk radios which provide fast, reliable information that can be shared quickly to save lives.

Fire

With our scalable satellite connectivity broadband systems and [wireless voice, video, data and internet solutions](/solutions/land-connectivity), security personnel and police can have access to robust and reliable control centre comms, and real-time sharing of critical information for effective and efficient management of any major incident or large-scale event.

Security and Police

Operations such as search and rescue require fast deployment and efficient co-ordination of many different services, including fire, ambulance and police crews. The ability to communicate between disparate radio networks becomes paramount to the success of the operation. 

We can provide satellite and radio solutions to enable on-the-move communications and continuity of operations in any condition. Many satellite phones [incorporate in-built SOS](/products/iridium-extreme-9575-satellite-phone) and tracking facilities that are ideal for personnel working in [remote or dangerous surroundings](/solutions/remote-and-lone-workers).


Search and Rescue

Government & Security

Sat comms can play a vital role in responding to environmental and humanitarian crises as well as their monitoring and prevention.  

NGO's & Environmental Solutions

[Response to disasters to provide humanitarian aid ](/insights/news/ast-distribution-asia-pte-ltd-ast-hdl-solutions-sdn-bhd-hdls-secure-flood-monitoring-deal-malaysian-government) requires a rapid response to arrange the many support services required such as co-ordinating personnel, building an infrastructure, arranging medical services, shelters and provisions.  

With infrastructure potentially damaged or unusable, AST Networks satellite comms solutions can help you coordinate an effective emergency response and keep your teams safe and connected. 

NGO's & Humanitarian

Co-ordinating operational activities and ensuring information is shared with other agencies is essential.  

For example, solutions such as the Iridium Extreme PPT deliver secure communications at the push of a button. It has been ruggedly engineered to support high intensity users in some of the harshest conditions in the world. Its ability to instantly communicate at the push of a button is not only more efficient but is also more cost-effective as it removes the need for expensive set-up costs – hardware for this solution is typically around 60% less than leading alternatives. 

Operations and welfare

AST Networks portable satellite communication solutions can aid in delivery of education to remote schools and educational facilities, enabling services such as live tutoring, scheduled broadcasts and e-learning portals as well as access to the internet. 

Education

Remote tracking of wildlife via satellite has also become a critical tool for environmental research and nature preservation. AST satellite communications solutions enable fast and reliable transfer of crucially important scientific data in remote regions. Our state-of-the-art global connectivity systems can also help quick deployment of logistics, easy coordination of operations, and increased safety for personnel. 

Environmental & Research

To support animal conservation efforts, our global satellite communication systems provide you insight into the location, health and welfare of animals.

We have assisted in many conservation projects including brown bears in Sweden and lions in Africa. Tracking collars, incorporating [Iridium](/en/services/i-1) short burst data (SBD) technology, provide scientists with a flexible solution to wildlife monitoring and studies in areas where GSM coverage is limited. The collars transmit invaluable data via satellite.

AST Networks has installed some of the most robust satellite-enabled sensors, coupled with reliable communication infrastructures, to allow monitoring of rainfall and water levels in [remote flood-prone areas such as Malaysia](https://www.ast-networks.com/en/insights/news/ast-distribution-asia-pte-ltd-ast-hdl-solutions-sdn-bhd-hdls-secure-flood-monitoring-deal-malaysian-government), enabling the collection, monitoring and interrogation of data, ultimately saving lives. 

Conservation and monitoring

Many climate change explorations and research functions are based in the polar regions, making voice and data communication impossible without satellite communications.

The [Iridium Certus®](/services/iridium-certus) service enables scientific data to be sent in the shortest time possible (at data speeds of up to 704 kbps) and relayed to the various institutes for processing. It also allows your crew and scientists to contact their families. 

Handheld satellite phones are critical, for communications and safety. Our unique solution, [IRIS](/solutions/m2-m-terminal-management), offers real-time location reports on a user-friendly portal and distress or SOS alerts.

Our [IoT](/solutions/land-io-t-and-asset-management) and machine-to-machine (M2M) solutions allow seamless connectivity to sensors for asset management. Automated monitoring allows for remote ice flow and probe data to be relayed in a timely, cost-effective manner.

Polar (Arctic and Antarctic) 

Reliable satellite and radio systems are vital for fast, effective delivery of aid where communications are poor or non-existent due to conflict or natural disaster. 

AST Networks satellite communication solutions provide key workers with instant communications to quickly deploy logistics processes, share data efficiently and co-ordinate operations, while assuring their safety. 

For environmental research and nature preservation, AST Networks satellite communications solutions enables fast and reliable transfer of crucially important scientific data in remote regions. 

We provide satellite communications to NGO and humanitarian organisations in the developing world.
