RS4 adds tilt compensation, faster initialization, and 5G readiness for future-proof surveying
About the EMLID Reach RS3
The EMLID Reach RS3 delivers professional-grade GNSS positioning with dual-band L1/L5 tracking for fast, reliable RTK fixes. The enhanced antenna design and improved fix times make the RS3 our workhorse for ground control point establishment.
With 22-hour battery life and IP68 waterproof rating, the RS3 handles full-day field operations in any weather conditions. The rugged design withstands the demands of construction sites, remote survey locations, and challenging terrain.
The successor EMLID RS4 builds on the RS3 platform with key improvements: tilt compensation eliminates the need to level the pole precisely, faster RTK initialization reduces wait times in the field, and 5G readiness ensures compatibility with next-generation correction networks. For survey teams prioritizing field efficiency, the RS4 delivers measurable productivity gains.
For new surveying projects, we recommend the EMLID RS4 for its enhanced tilt compensation and faster initialization. Contact us to discuss your ground control and surveying requirements—we can advise on the optimal GNSS configuration for your project.
Key Benefits
- Dual-band L1/L5 for fast, reliable RTK fixes
- 5mm + 0.5ppm survey-grade accuracy
- 22-hour battery handles full-day operations
- IP68 waterproof for any weather conditions
- Multi-constellation tracking maximizes satellite availability
- Can function as base station or rover
- ReachView 3 app for intuitive field operation
Considerations
- No tilt compensation—pole must be held level for accurate measurements (RS4 adds this feature)
- The RS4 achieves faster RTK initialization and adds 5G readiness for future correction networks
- Previous generation—EMLID prioritizes RS4 for firmware updates and new feature development

EMLID Reach RS3 Frequently Asked Questions
Is the EMLID Reach RS3 discontinued?
The RS3 has been superseded by the EMLID RS4 as the current-generation receiver. While RS3 units remain functional, EMLID's development focus has shifted to the RS4 platform with tilt compensation and 5G readiness.
EMLID RS3 vs RS4: what are the differences?
The RS4 adds tilt compensation (measure without leveling the pole), faster RTK initialization, 5G readiness for next-gen correction networks, and an improved antenna design. Both achieve survey-grade accuracy, but the RS4 offers significantly better field efficiency.
Should I upgrade from EMLID RS3 to RS4?
If field efficiency matters to your workflow, the RS4's tilt compensation alone can save significant time per point. The 5G readiness also future-proofs your investment as correction networks evolve. For high-volume survey work, the upgrade pays for itself quickly.
Can EMLID RS3 work as a base station?
Yes. The RS3 can function as either a base station transmitting corrections or as a rover receiving them. This flexibility allows various configurations: base/rover pair, single rover with NTRIP, or network RTK setups.
How do I get RTK corrections with EMLID RS3?
Three options: (1) Use an EMLID base station transmitting via radio or internet, (2) Connect to NTRIP correction service via cellular, or (3) Use post-processing for cm accuracy without real-time corrections.
Is EMLID RS3 accurate enough for engineering surveys?
Yes. The 5mm + 0.5ppm accuracy meets survey-grade requirements for most engineering applications including construction staking, boundary surveys, and ground control. Licensed surveyors regularly use EMLID receivers for professional work.
How long does EMLID RS3 battery last in the field?
The RS3 provides 22 hours of continuous operation—enough for multiple full-day jobs on a single charge. The battery status is displayed in the ReachView 3 app for monitoring during field operations.
