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 struggled to gain commercial traction but by adopting a hybrid approach using the technical strengths of each sensor system will deliver a gravity sensing system which meets the end-users needs.The Quantum gravity sensor has the ability to a) provide levels of sensitivity unachievable today with MEMS sensors, b) measure with very low levels of drift and c) provide absolute gravity and gravity gradiometer measurements. However, its form factor, lack of mobility and cost provide a challenge where surveying of larger areas is required. MEMS gravity sensors lack the absolute accuracy of Quantum sensors and have larger drift levels but have a form factor, power consumption and cost which enable them to be deployed either as a single sensor or swarm on drones or autonomous vehicles, stopping to make measurements and then moving again. As a result of these different attributes, a hybrid approach can take advantage of the relative strengths to provide a truly innovative system for use in real world environments.The Quantum system will be used as a Base station providing an absolute gravity reference for the MEMS sensors. The Quantum Base station (the hive) will have limited mobility being either stationary or mobile of a rail. The MEMS sensors (the bees) will leave Base station on autonomous vehicles or drones, stop to take stationary measurements at pre-defined locations and then return to the Quantum Base for drift elimination.By adopting this hybrid approach, the project will meet the needs of the end customers who require gravity surveys over a large area in an acceptable time period and at a viable cost. End customers are multiple but include civil engineering companies, utilities, environmental organisations, carbon capture facilities and defence/security entities.

量子Hive项目是伯明翰大学（UOB）和硅​​微重力（SMG）之间的联合计划。它旨在提供一种创新的，可行的方向，以通过采用SMG开发的MEMS重力传感器采用混合方法来商业化在UOB开发的冷原子量子传感器。重力传感器在历史上一直在努力获得商业牵引力，但通过使用每个传感器系统的技术优势采用混合方法，将提供一个满足最终用户需求的重力传感系统。量子重力传感器具有a）的能力a）a）提供了敏感性的水平，如今，MEMS传感器的敏感性无法实现，b）量度低，b）量度较低的量度和c）置于漂复程度和c）。但是，在需要对较大区域进行测量的情况下，其形态，缺乏流动性和成本为挑战提供了挑战。 MEMS重力传感器缺乏量子传感器的绝对准确性，并且具有较大的漂移水平，但具有形式，功耗和成本，使它们能够作为单个传感器部署或在无人机或自动驾驶汽车上部署，以进行测量，然后再移动。由于这些不同的属性，混合方法可以利用相对优势，为在现实世界环境中使用真正的创新系统。量子系统将用作基站，为MEMS传感器提供绝对重力参考。量子基站（蜂巢）将有限的移动性（固定或移动设备）有限。 MEMS传感器（蜜蜂）将在自动驾驶汽车或无人机上离开基站，停止在预定义的位置进行固定测量，然后返回到量子基地进行漂移消除。通过采用这种混合方法，该项目将满足最终客户的需求，这些客户需要在可接受的时间内进行大型范围内的重力调查，并在可接受的成本和有货物的成本上进行。最终客户是多重的，但包括土木工程公司，公用事业，环境组织，碳捕获设施和国防/安全实体。
