If you’re in the market for a GNSS receiver, you’ve probably come across the Emlid Reach RS3 and Reach RS2+. Both are top-tier options, but each has distinct features that could make or break your decision depending on your needs. In this article, we’ll break down the key differences between these two models in a way that’s easy to understand. We’ll also provide a critical look at their strengths and weaknesses, helping you decide which one is truly worth your investment.
The Differences Between Emlid Reach RS2+ and Reach RS3 for Your Project
1. Tilt Compensation: A Game-Changer for Reach RS3
One of the most talked-about features of the Reach RS3 is its IMU tilt compensation. This feature allows you to get centimeter-level accuracy even when the receiver is tilted up to 60 degrees. No need for constant calibration, and it’s immune to magnetic interference. That means metal objects or electronics nearby won’t affect its accuracy. If you’re working in tough environments with uneven terrain, this feature alone makes the RS3 a powerful choice.
In contrast, the Reach RS2+ lacks tilt compensation. This means you’ll need to keep the device level at all times to get accurate results. While the RS2+ still delivers great accuracy, the lack of tilt compensation is a noticeable drawback if you’re working in tricky conditions.
Verdict: If your work involves surveying in areas where the terrain is uneven or there are obstacles, the RS3 is the clear winner here.
2. Speed and Precision: How Fast Do You Need a Fix?
The Reach RS3 gets a centimeter-accurate fix in about 5 seconds. Even in challenging conditions like partial sky obstruction or when the device is tilted, it holds up well. The RS3 supports GPS, GLONASS, BeiDou, and Galileo, ensuring reliable performance across a variety of GNSS systems.
The Reach RS2+ is no slouch either but doesn’t quite match the RS3’s speed. It’s still quick, though, delivering centimeter-level accuracy over distances up to 60km in RTK and 100km in PPK. The RS2+ also tracks all the major GNSS signals, but in complex environments, it might struggle a bit more than the RS3.
Verdict: If you need speed and reliability in tough conditions, go for the RS3. If your focus is more on long-range projects, the RS2+ is a solid choice, even if it’s not as fast to get a fix.
3. Battery Life: Who Can Last Longer in the Field?
Battery life is crucial when you’re working long hours in the field. The Reach RS3 comes with an impressive 18 hours of work as an RTK rover with tilt compensation and 22 hours of data logging. If you need even more power, you can plug in a USB-C power bank to keep it running for days.
The Reach RS2+ is comparable in this regard. It offers 16 hours of work as an RTK rover and also lasts 22 hours when data logging. Like the RS3, it supports USB-C charging, so you can power it with a wall charger or a power bank in the field.
Verdict: Both models deliver excellent battery life, but the RS3 edges out the RS2+ by offering more working hours with tilt compensation. If your projects demand that extra edge in longevity, the RS3 is the better bet.
4. Connectivity: LTE and Radio Options
The Reach RS3 has a built-in LTE modem, which allows it to receive or broadcast corrections through NTRIP. But where it really shines is with its dual-band radio, which supports both LoRa (868/915MHz) and UHF (450MHz). This dual-band capability is a game-changer if you’re working in remote areas without reliable internet coverage. You can still receive corrections between two receivers, making it ideal for rural or hard-to-reach areas.
The Reach RS2+ also has an LTE modem with 4G, 3G, and 2G compatibility, allowing you to access corrections over NTRIP without relying on a smartphone. However, it lacks the dual-band radio, which limits its flexibility when internet connectivity is a challenge.
Verdict: If you often work in areas with poor internet coverage, the RS3 is the better choice with its dual-band radio. The RS2+ is good for urban areas or locations with reliable internet, but the lack of dual-band support is a limitation.
5. Durability: Can They Handle Harsh Conditions?
Both the Reach RS3 and Reach RS2+ are built to withstand tough conditions. Each device has a polycarbonate body coated with elastomer, making them rugged, impact-resistant, and ready for the harshest environments. They are both IP67-rated, meaning they’re fully dustproof and waterproof, and can handle extreme temperatures ranging from -20°C to 65°C (-4°F to 149°F).
Verdict: It’s a tie here. Both models are built to last and can perform under extreme weather conditions.
6. Post-Processing and RINEX Logging
When it comes to RINEX logging and post-processing, both the RS3 and RS2+ perform well. The Reach RS3 supports RINEX logging and is compatible with post-processing services like OPUS, AUSPOS, and PPP. You can also use Emlid Studio or any other RINEX-supported software for easy data handling.
Similarly, the Reach RS2+ offers RINEX logging and works smoothly with OPUS, AUSPOS, and PPP. Additionally, it is registered in NOAA’s National Geodetic Survey, which enhances its credibility and post-processing efficiency.
Verdict: Both models offer excellent post-processing support, so whichever you choose, you’ll have all the tools you need for precise, professional results.
Which One Should You Choose?
So, which is better, the Reach RS3 or the Reach RS2+? It all depends on your needs. If you work in complex, uneven environments, need tilt compensation, and value the speed of getting a fix, the Reach RS3 is clearly the superior choice. If you prioritize long-range accuracy and don’t need tilt compensation, the Reach RS2+ is still a fantastic option, especially if you’re working with a tighter budget.
While the RS3 outshines the RS2+ in several areas, both are excellent receivers. For those who want the latest and greatest, the Reach RS3 provides better features like IMU tilt compensation and dual-band radio, making it ideal for advanced surveying tasks. But if you need solid performance at a lower cost, the Reach RS2+ remains a highly capable, rugged receiver that can handle almost anything you throw at it.
