• SlingShot

    beyond line of sight communications for First Responders

SlingShot for Aid & Emergency

SlingShot is a lightweight unit that converts existing in-service radios to SATCOM, offering a straightforward and cost-effective way to achieve global, secure, BLOS (Beyond Line of Sight) communications for those using UHF and VHF radios.

Why You Need SlingShot


Slingshot is a unique and innovative solution that enables widely dispersed personnel to communicate effectively in high tempo operations.


SlingShot is a small and lightweight unit that converts existing radios to secure, real-time, BLOS, COTM devices, in all situations and locations.


SlingShot delivers all the benefits of SATCOM, but on-the-move and using standard UHF and VHF radios. With flexible airtime pricing and guaranteed bandwidth, it is more available, more reliable, and more functional than using Satphones.

  • Voice and Data BLOS and COTM

    communicate securely over land, sea and air

  • Radio Agnostic and Transparent

    converts UHF & VHF radios to L-Band Satcom

  • Flexible Airtime Leasing

    only when and where you need it

  • Infrastructure independent

    no infrastructure? no problem

  • Small size & weight with low power consumption

    move quickly, minimise weight

  • Dedicated bandwidth

    deploy securely with guaranteed bandwidth for high quality sound and data

  • Achieve beyond-line-of-sight communications without having to re-equip or re-train

  • Use in-service radios. Enables interoperability between agencies using differing comms.

  • Vastly reduce the cost of Satcom by using L-Band commercial satcom and only leasing the areas you require, for the time you need them

  • Because SlingShot uses Inmarsat’s I4 constellation of satellites, it doesn’t matter where in the world you deploy, or what distance you need to maintain voice and data comms; you will not have to rely on local infrastructure, or deploy and protect your own.

  • Move quickly and maximise the payload. No extra batteries, chargers or handsets to weigh you down and take-up valuable space.

By converting in-service UHF and VHF radios into Satcom devices, SlingShot delivers BLOS (Beyond Line of Sight) voice and data communications.

Range is extended from tens to hundreds and thousands of miles, without further equipping or re-training.

SlingShot has Manpack, Vehicle, Maritime and Aviation configurations.

The omni-directional antennas mean that COTM (Communications on the Move) is truly effective with no loss of signal or quality.

No need to alter direction or pause to locate a beam.

SlingShot is a simple concept, in that it provides BLOS and COTM capability to existing UHF and VHF radios, without any change to in-service equipment or security.

The radio operates in exactly the same way as it does in line of sight mode, providing a significant range extension.

Depending on the satellite option chosen this could be many thousands of miles within a single satellite footprint or globally if switched between satellites.

Real estate on mounted platforms is limited and dismounted personnel face a real challenge if technology reduces the amount of food , water and supplies that can be carried. The SlingShot footprint is minimal and the manpack system can take power from radio batteries, so the operator isn’t required to purchase/carry different battery types and support different charging systems.

A full manpack system weighs under 2kg with operational life of up to 24 hours between charges

Inmarsat’s L-TAC service can be leased for a fixed period (minimum duration one month), providing assured access throughout.

Slingshot, combined with Inmarsat’s L-TAC lease service, is fully flexible and designed to cost effectively meet security and reliability requirements.

So many operations, in which today’s first responders find themselves, include coordination with multiple agencies, some of which will have different radio systems.

Slingshot can bring these disparate systems together without additional re-equipping and without a heavy training tariff.

VHF and UHF radios of different manufacture can use Slingshot to convert to BLOS devices that can communicate with each other.  Systems are available for Manpack, Vehicle and Maritime, meaning travelling teams can maintain contact. Aviation will be available soon.
