The RockFLEET Tracker is a truly global tracking device designed for permanent use aboard marine vessels and land vehicles. Its optional LTE Narrowband unit allows it to use mobile phone networks when possible, automatically switching to the global Iridium satellite network when necessary (lowest-cost routing).

It’s waterproof, ruggedised, and has a variety of mounting options to suit your needs.

Designed for permanent installation on ships, yachts, vehicles, and other assets

The tracker will wake up on a regular basis, obtain a position using the GPS satellite network, and then transmit that position back to Ground Control HQ using either LTE Narrowband/GPRS or the Iridium satellite network. We visualize the positions on an easy-to-use web-based viewer.

The RockFLEET also allows short messages (like SMS, social media updates, and short emails) to be sent using a paired Bluetooth device, such as a smartphone, and the Messenger app. This allows for full two-way communication wherever you are, even when out of mobile network range.

The combination of LTE Narrowband and Iridium provides a cost-effective and truly global method of tracking and communicating with your assets wherever they are.

Ground Control offers Iridium SBD airtime both as a prepaid tariff, and as an annual contract for companies planning a larger deployment of devices. Full pricing plans can be found on our Short Burst Data Pricing page.

If you choose our prepaid, or pay-as-you-go option, line rental is paid in blocks of 1 month, and allows the RockFLEET to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the RockFLEET. No annual contract is required. Line rental costs £18.00 per month and includes access to The CORE management system for managing your devices.

Credits are used each time you transmit. 1 credit is used per 50 bytes (or part thereof) of message sent or received. 1 credit is also used if you check your mailbox and there are no messages waiting (A mailbox check). Credits do not expire, even if you are paying no line rental. Credits are shared/pooled between all of the devices on your account

Please note, while our pay-as-you-go tariffs offer great flexibility for development purposes, we know they are not suitable for everyone. If you are planning a larger deployment of devices and are willing to commit to airtime contracts of 12 months or more, please get in touch; our annual contracts are likely to suit you better.
