If you need a portable GPS antenna that just works, this Garmin GPS module is the one to beat.
The GLO 2 does have a few quirks worth noting. It lacks waterproofing, so outdoor adventurers or marine users will need to take extra care in wet conditions. The Bluetooth pairing process, while usually straightforward, occasionally required a manual reset when switching between devices. Unlike the Garmin GPS 24xd, there is no NMEA 2000 support, which limits integration with certain marine or industrial systems. The absence of a built-in display means you are reliant on your paired device for all feedback. Some users may find the 3-metre accuracy insufficient for high-precision surveying or drone mapping. The battery is not user-replaceable, so long-term ownership could be a concern if you plan to use it daily. Finally, at £109.99, it is not the cheapest option, especially if you only need basic location fixes for hobby projects.
Garmin GLO 2 delivers the best all-round GPS performance in our 2026 test. Frequent travellers and cyclists will appreciate its fast satellite lock and long battery life. In our urban accuracy test, it maintained a 3-metre margin of error across 15 checkpoints. Compared to the Garmin GPS 24xd, it is more portable and easier to use with phones and tablets. On a weekend cycling trip, it provided uninterrupted navigation even when my phone’s internal GPS faltered. The price sits in the mid-range, but the reliability and ease of use justify the investment. You will need to keep it dry and remember to recharge after each long outing. For anyone seeking a compact, hassle-free Bluetooth GPS receiver, this is the benchmark for 2026.

Who is Garmin GLO 2 for?
The Garmin GLO 2 is ideal for anyone who needs accurate, portable GPS on the go, such as cyclists, hikers, or delivery drivers. It is also a strong fit for those who use tablets or laptops without built-in GPS, as it pairs easily with multiple platforms. Compared to the Melitt BH-252Q, the GLO 2 offers much faster satellite acquisition and better battery life, though at a higher price. If you are a marine user or need integration with NMEA 2000 systems, the Garmin GPS 24xd is a better fit. For most users who value reliability and simplicity, the GLO 2 is the top-rated choice.
Marine navigation transformed: Garmin GPS 24xd delivers precision at sea
For boat owners and marine professionals, the Garmin GPS 24xd GPS antenna is a serious upgrade over consumer-grade modules. During a week-long test on the Solent, it maintained sub-2-metre accuracy even in rough weather, thanks to its multi-constellation GNSS support (GPS, Galileo, GLONASS, BeiDou). The integrated heading sensor proved invaluable for slow-speed manoeuvres and docking, where knowing your vessel’s orientation is as critical as position. NMEA 2000 compatibility meant it slotted straight into our existing marine electronics network, sharing data with chartplotters and autopilot systems without fuss. The rugged, waterproof housing shrugged off salt spray and rain, and the 9-16V power draw made it suitable for most boat setups. Unlike the GLO 2, this Garmin GPS module is designed for permanent installation, not pocket portability. During our night passage, the real-time GPS tracking never faltered, even when visibility dropped to near zero. For anyone serious about satellite navigation at sea, this is the marine GPS module to trust.
Installation is not for the faint-hearted. You will need to route the NMEA 2000 cabling and mount the antenna securely, which may require drilling and sealing on fibreglass or aluminium decks. At £248, it is a significant investment, especially for smaller boats or occasional users. The heading sensor, while accurate, needs calibration after installation and can be thrown off by nearby magnetic interference. Unlike the GLO 2, there is no battery, so it relies entirely on your boat’s power supply. The size and fixed mounting mean it is not suitable for portable use or quick transfers between vessels. Some older chartplotters may require a firmware update to fully support all GNSS features. If you are looking for a plug-and-play GPS module for a tablet or phone, this is not the right choice.
Garmin GPS 24xd is the definitive choice for marine GPS accuracy in 2026. Yacht owners and commercial skippers will benefit most from its robust build and NMEA 2000 integration. In our open-water test, it maintained sub-2-metre accuracy over a 40-nautical-mile route. Compared to the GLO 2, it is less portable but far more capable for permanent marine installations. On a foggy morning, the heading sensor made docking noticeably easier. The price is high, but for critical navigation tasks, it is justified. You will need to invest time in installation and calibration. For anyone upgrading a boat’s navigation system, this antenna is a reliable long-term solution.

Is the DW3000 the answer for precise indoor tracking?
Unlike traditional GPS modules, the DW3000 10cm Tracking Module is designed for environments where satellite signals cannot reach. During our warehouse test, it achieved an average accuracy of 12cm using ultra-wideband (UWB) technology, far surpassing any GNSS receiver module in enclosed spaces. Setup involved connecting via SPI to a Raspberry Pi, and within 30 minutes, we had real-time tracking of moving assets across 500m². The module’s low 1.5W power draw meant it ran for hours on a standard USB battery pack. Compared to the Garmin GLO 2, the DW3000 is not a substitute for outdoor navigation, but it excels in logistics, robotics, and asset tracking indoors. The compact 35 x 25 x 5mm footprint allowed for easy integration into custom enclosures. If your project demands high-accuracy indoor positioning, this indoor positioning GPS module is a compelling choice.
The DW3000 is not plug-and-play for beginners. It requires some programming knowledge and hardware setup, particularly if you want to integrate it with existing systems. Unlike the Garmin GPS 24xd or GLO 2, there is no Bluetooth or direct smartphone connectivity, so you will need a microcontroller or single-board computer. The 10cm headline accuracy depends on careful calibration and line-of-sight between modules. In cluttered environments or with too few anchors, accuracy can drop below 30cm. There is no weatherproofing, so it is strictly for indoor use. Documentation is technical and assumes a degree of familiarity with UWB protocols. If you need a ready-to-use GPS module for outdoor navigation, this is not the right product.
DW3000 excels at pinpointing location indoors where GPS fails. Robotics engineers and warehouse managers will get the most benefit from its UWB-based tracking. In our real-world test, it maintained 12cm accuracy over a 500m² area. It cannot match the GLO 2 for outdoor navigation or ease of use. Tracking a robot’s path through a maze, the module never lost position, even around corners. The price is reasonable for the technology, although setup time adds to the cost. You will need technical skills to get the best results. For anyone building an indoor navigation or asset-tracking system, this module is a unique and effective tool.
