RTK for real-time observation
The RTK accuracy of H: 8 mm ± 1 ppm and V: 15 mm ± 1 ppm allows supporting surveys and point checks with real-time corrections. Feature 2
The STEC SDc takes field productivity to another level. Its compact and lightweight format combines GNSS positioning, tilt compensation, and dual camera in a receiver designed to make daily work easier.
What makes it unique
Dual camera for visual support in the field
It integrates a front camera and a bottom camera, both with a 77° field of view and 1280 × 720 resolution, facilitating workflows with visual support and augmented reality functions. Markdown pegado
Compact and lightweight 429 g format
At only 98.9 × 98.9 × 51.6 mm and 429 g, the SDc concentrates GNSS, IMU, camera, and connectivity capabilities in a compact receiver that is easy to carry throughout the workday. Markdown pegado
IMU with tilt up to 120°
Its IMU allows working with the pole tilted up to 120° and specifies an accuracy of 2 cm within 60°, providing greater flexibility when measuring points where keeping the pole completely vertical is impractical. Markdown pegado
Visual support with dual camera
The front and bottom cameras offer a 77° field of view and 1280 × 720 resolution, providing visual support for different field workflows. Markdown pegado
Measurement with tilted pole
The IMU supports up to 120° of tilt and specifies 2 cm within 60°, making measurement easier when keeping the pole completely vertical is impractical. Markdown pegado
Compact to accompany you in the field
Its dimensions of 98.9 × 98.9 × 51.6 mm and a weight of only 429 g make it easy to transport and handle during survey days. Markdown pegado
Ready for demanding terrain
It features IP68 protection, operation between -30 °C and 65 °C, and resistance to 1.8 m drops onto hard surfaces, providing physical support for demanding workdays. Markdown pegado
Especially
created for you
IMU for tilted positions
Up to 120° compensation makes it easier to measure when the pull cannot be held vertical, with a specification of 2 cm within 60°.
UHF and Wi-Fi for corrections
The 410–470 MHz UHF radio and 2.4/5 GHz Wi-Fi offer link alternatives with controllers and networks during surveying operations. Markdown pasted
RTK and PPK in the same receiver
Allows switching between RTK measurement and PPK processing depending on the workflow, while preserving the precision specifications defined for both modes.
Data logging and transfer
Integrates 32 GB SSD, USB Type-C transfer and FTP/HTTP download to manage files generated during measurement campaigns.
Wide thermal range operation
Its operating range of -30 °C to 65 °C allows it to support field work under varied thermal conditions. Markdown pasted
Integrated UHF radio
The radio operates at 410–470 MHz with an indicated output of 1 W, offering an additional link to receive and transmit corrections in the field.
Dust and water resistance
IP68 protection helps safeguard the receiver against dust and water ingress in demanding work environments.
Operating temperature range
The team specifies operation between -30 °C and 65 °C and storage between -40 °C and 80 °C for work and transport under variable conditions. Markdown pasted
Multi-constellation GNSS
Works with GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS, and IRNSS, expanding the signals available for positioning tasks.
PPK for post-processing
PPK mode specifies H: 3 mm ± 1 ppm and V: 5 mm ± 1 ppm, useful when the workflow involves processing observations after fieldwork.
Formats for data flow
Supports DAT, RINEX 2.x, RINEX 3.x and BINEX, as well as RTCM and NMEA 0183, facilitating the exchange of observations and corrections. Markdown pasted
Compact format for work
With 98.9 × 98.9 × 51.6 mm and 429 g, the receiver is easy to transport between work fronts and control points.
Ground protection
IP68 protection and resistance to drops of 1.8 m onto hard surfaces provide physical backup for workdays on construction sites.
Network RTK
Network RTK specifies H: 8 mm ± 0.5 ppm and V: 15 mm ± 0.5 ppm, useful for position checks when there is access to network corrections. Markdown pasted

Our GNSS devices that use a SIM chip and have an IMEI must be registered to operate on Chile's mobile networks, in accordance with article 7 of the Exempt Resolution No. 1,463 of 2016 from SUBTEL. Registration is done through a certification company authorized by SUBTEL.
To register them:
- Go to official list of certifying companies and choose one.
- Request the registration of the GNSS equipment, providing its IMEI and the information indicated to you.
- Wait for registration confirmation to avoid your mobile connection being blocked.
If the equipment is sold in Chile, the registration corresponds to the marketer. More information at SUBTEL.
