Spectra Precision has launched a new GNSS receiver, the SP60. Designed to meet the evolving needs of surveyors, the SP60 is a versatile solution combining next generation Spectra Precision GNSS technology, a high level of configuration flexibility and an innovative design. It offers many of the features found in it's bigger brother, the SP80, at a fraction of the cost.
The SP60 is part of Spectra Precision’s latest portfolio of GNSS receivers specifically designed for the mainstream survey and construction applications such as cadastral, topographic, control, stakeout and network RTK.
A key feature is exclusive Z-Blade GNSS-centric technology running on a new-generation, 240-channel 6G chipset. The receiver is capable of fully utilizing all six available GNSS systems (GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS), but can also be configured to use only selected constellations in an RTK solution (GPS-only, GLONASS-only or BeiDou-only).
With L-Band capability to enable CenterPoint RTX correction service, the SP60 GNSS receiver can deliver centimeter-level accuracy without terrestrial/cellular network availability. The receiver is optimized to provide high accuracy positioning performance worldwide.
Configuration flexibility allows the SP60 to be used in multiple configurations and operating modes from a simple post-processing solution to a network RTK or CenterPoint RTX capable rover. In addition, the optional transmit radio or embedded Long Range Bluetooth enables the SP60 receiver to be used as a base and rover system. The extended scalability allows surveyors to begin with a simple solution, and through hardware and firmware upgrades, adapt the SP60 to more complex survey jobs. Extremely scalable and versatile, SP60 can respond to any type of surveying job, starting with a simple L1 GPS only post-processing solution up to dual-frequency GNSS network RTK rover.SP60 integrates powerful Long Range Bluetooth capabilities opening new operation modes to surveyors.
The Spectra Precision SP60 is rugged and waterproof, compact, lightweight and ergonomic for ease of use in the field. The received also includes a patented inside-the-rod mounted UHF antenna. When the UHF transmit radio module is used, its UHF antenna remains protected inside the rugged rod, extending the radio range performance.
Combining the unique all-signals-tracking and processing Z-Blade GNSS-centric technology and L-band capability for satellite-delivered RTX service, the SP60 receiver provides the most reliable measurements and the highest possible accuracy under any conditions and in any place the world.
Now, the Bluetooth wireless communication can be used as an alternative radio link between base and rover for a few hundred meters range making this solution very attractive for small site surveys.
Easier and simpler than UHF radio, and without any need for a license this can be a very efficient way to quickly setup a short range base rover solution.
The patented UHF antenna, set inside the fiberglass rod, extends the range of RTK radio performance and provides protection at the same time. All these enhancements make the design of SP60 GNSS receiver unique and powerful.
“The SP60 was designed as an extremely versatile receiver, allowing surveyors to make it suitable for a specific surveying project, and then upgrade it to a more complex solution, when needed," says Olivier Casabianca, business area director of Trimble's Spectra Precision Division.
Z-Blade is a patented, proprietary GNSS engine that is the core GNSS data processing technology implemented in SP60. Z-Blade is a GNSS-centric engine which processes all the available signals equally without preference to the GPS constellation. This technology has resulted in the ability to provide positions of admissible quality (standalone as well as RTK) in harsh conditions where satellite visibility is low due to obstacles like trees, buildings, etc.
What GNSS signals are supported by the SP60 receiver?
SP60 supports the following GNSS signals:
Details of signal frequencies supported by the SP60 receiver:
The following formats are supported by the SP60 as a rover
The SP60 as a base can output data in the following formats:
Yes. A RINEX Converter tool is available (Partners site), which supports the ATOM format and newer versions of the RINEX format. The current version of the RINEX converter (v4.6.4) does not support SP60 antenna parameters so conversion with the slant antenna model is not possible.
This function needs to first be activated using Survey Pro, Go to the Settings/Anti-Theft or Survey/Anti-Theft menu:
Please also refer to the SP60 User Guide for more details and for the FAST Survey workflow.
If you lose your password, you will be unable to remove the Anti-Theft protection. You will need to contact Technical Support to have a specific password provided for you to disable this protection.
The SP60 receiver features a 2600mAh Li Ion battery. The battery life is about 8 hours with GNSS and internal UHF modules ON in receive mode. Without UHF, the battery life is 10 hours. There is not a hot swap capability available on the SP60
Yes, if you use the SP60 without the optional UHF module.
No, if your receiver has the UHF module installed. Because the UHF antenna connector was designed to be aligned with the vertical axis of the range pole, a standard range pole with its external 5/8" tapping cannot be screwed into the base of the SP60 nor is it possible for the UHF antenna to fit inside a standard range pole. With the UHF module installed, you must fix the receiver on top of the Spectra Precision 2m fiberglass range pole provided in the UHF kit (rover configuration), or on top of the special 25cm pole extension with the oblong hole (base configuration). The UHF antenna then fits inside the pole for optimal radio propagation.
The SP60 receiver is rated IP67 except for the battery compartment which is not waterproof. This means that water could enter the battery compartment but will not enter the receiver and therefore will not introduce any electrical risk to the receiver itself. The only possible damage could be to the battery itself which is not waterproof.
No, you cannot. The frequency must be set by an authorized dealer based on your licensed frequencies. The current channel in use can be easily changed in the field using the data collector software.
To control the SP60, you can use a range of rugged Spectra Precision data collectors and the following field software:
Spectra Precision Survey Office software (version 3.50 and higher) should be used to process data collected with the SP60.
To download (or delete) raw data and log files from the receiver’s internal memory, you can use:
Data files can also be downloaded directly onto a USB key connected to the SP60. SP File Manager PC tool is available from the support page on www.spectraprecision.com or from the Partners web site.
A new tool is available to upgrade firmware on the SP60: Spectra Precision Loader (This tool also supports MobileMapper 300, ProMark 700 and SP80).
Please refer to the SP60 User Guide for the detailed workflow to follow.
New SP60 firmware versions and related software such as FAST Survey, Survey Pro or Survey Office software are periodically made available at the Spectra Precision website on the Support tab for the specific product web-page. Release Notes including upgrade instructions can also be found there.
Spectra Precision Loader is used to install new options.
Bluetooth is built into all SP60 receivers and does not require a license. Bluetooth connection between two SP60 receivers is very easy and does not require any settings. Simply create Bluetooth rover and Bluetooth base profiles in Survey Pro and connect. Compared to UHF, it is simpler and completely free of charge.
The Bluetooth used in the SP60 is Class 1 (100 mW) which provides a range of several hundred meters. This is much shorter than what can be achieved with the internal UHF module but it is very convenient for small construction sites and is free.
L-Band is a frequency range between 390MHz and 1.55GHz which is used for satellite communications. Trimble RTX service uses L-Band at 1525 – 1560 MHz to broadcast differential corrections by satellite. Most of the regions of the world are covered by several geostationary satellites as shown below:
Several RTX services are available and subscriptions are available directly from https://store.trimble.com. The SP60 supports CenterPoint RTX via L-Band or IP delivered (cellular). Activating a subscription can be achieved by entering an activation passcode via the SP Loader PC tool. CenterPoint RTX provides 4cm accuracy after 30 minutes of convergence time. It also requires L2 to be activated on the SP60.
Accuracy and performance are the same with both correction streams. However, there are significant differences in operating modes.
Pros: Available anywhere regardless of cellular coverage. Cellular service subscription is not required.
Cons: Need to have RTX satellite (geostationary) visibility.
RTX over IP
Pros: Corrections can be received in urban areas or under canopy where cellular is available
Cons: Cellular coverage is required.
