Projects

2024 Collaborative R&D Lead participant

Navigation grade 100G MEMS accelerometer for Inertial Navigation

1 Jul 2024 to 31 Dec 2025

Awarded
£384,124
Total cost £768,249

This innovative project will deliver a 100g MEMS (micro-electrical mechanical systems) accelerometer, bringing MEMS technology into the navigation grade inertial sector and providing UK sovereign capability in a key technology area. Operating in GPS denied environments has become a critical area of focus with Inertial Navigation (INS) providing a resilien...

2024 Collaborative R&D Lead participant

Gravity sensing for rail construction demonstration

1 Jan 2024 to 31 Mar 2025

Awarded
£156,111
Total cost £223,016

Understanding the subsurface is critical to rail construction. A better understanding can reduce the risk of unknowns, saving time and money through the design, construction and lifetime of rail assets. In the UK rail industry this is clearly demonstrated by HS2\. In HS2 Phase One naturally occurring karsts in the Chilterns have led to subsidence and adve...

2023 Collaborative R&D Lead participant

QUAMINEX - a drone deployed integrated gravity/ magnetics measurement system for mineral exploration

1 Oct 2023 to 31 Mar 2025

Awarded
£414,106
Total cost £591,580

The need for new mineral resources is key to the energy transition away from hydrocarbons. Unfortunately many of the easy to find mineral deposits have been already exploited leaving the world with the challenge of finding new deposits for batteries and electrification. Magnetic and gravity sensing have long been identified as tools for detecting mineral ...

2023 Collaborative R&D Lead participant

Gravity sensing for rail construction feasibility study

1 May 2023 to 31 Jul 2023

Awarded
£24,897
Total cost £36,083

Identifying subsurface hazards is a critical issue for railway construction. Finding unexpected features during construction can have major cost and time impacts. Similarly, if not identified hazards can cause subsidence and deformation during the life of the track. Subsurface hazards may be man-made such as old minings or tunnels or natural in the form o...

2023 Innovation Loans Lead participant

Autonomous Gravimeter for Tunnel and Bunker detection

6 Apr 2023 to 6 Apr 2024

Awarded
£563,520
Total cost £841,075
2022 Collaborative R&D Lead participant

Quantum Hive gravity system

1 Nov 2022 to 30 Apr 2024

Awarded
£174,929
Total cost £249,898

The Quantum Hive project is a joint initiative between the University of Birmingham (UoB) and Silicon Microgravity (SMG). It aims to deliver an innovative, viable way forward for commercialising the cold atom Quantum sensor developed at the UoB by adopting a hybrid approach with MEMS gravity sensors developed by SMG. Gravity sensors have historically stru...

2021 Collaborative R&D Lead participant

Navigation grade MEMS Gyro

28 Jun 2021 to 28 Dec 2022

Awarded
£750,000
Total cost £859,830

There is an increasing need to accurately measure movement and position in a broad range of applications including aerospace, automotive, robotics, underwater to name a few. Key to this are Inertial Navigation systems that do not rely on global positioning systems to measure movement and determine location. Within Inertial Navigation systems, the key tech...

2018 Collaborative R&D

Pioneer Gravity: Gravity sensors for infrastructure productivity, situational awareness and seeing the invisible

1 Nov 2018 to 31 Dec 2021

Awarded
£349,450
Total cost £499,214

"Despite our increasing ability to detect and monitor objects that exist on land, sea, around buildings or in space, our ability to detect objects beneath the ground has not improved significantly. When it comes to attempting to locate a buried and forgotten pipe, telling the extent of a sink hole or assessing the quality of infrastructure we still often ...

2017 Feasibility Studies Lead participant

MEMS gravity sensors

1 Jan 2017 to 31 Mar 2017

Awarded
£14,000
Total cost £20,000

Silicon Microgravity Ltd. is a spin-out from Cambridge University. The company has developed a high-performance microelectromechanical systems (MEMS) accelerometer with a projected resolution of 1 billionth the Earth's gravitational field. The company is currently developing a borehole gravity tool for oil and gas applications. This project seeks to estab...

2016 Collaborative R&D Lead participant

Improving reservoir management

1 Jan 2016 to 31 Mar 2019

Awarded
£290,977
Total cost £484,638
