John Deere Introduces The StarFire 7000 Receiver

• RTK-like accuracy - 2.5 cm pass to pass repeatability
• SF-RTK achieves 75% faster pull-in times, compared to SF3 signal
• Guaranteed 5-year repeatability, season to season
• Drop-in replacement for StarFire 6000 receiver

The StarFire 7000 Receiver is the latest addition to the suite of Precision Ag Technology from John Deere. The StarFire 7000 Receiver offers greater accuracy, faster pull-in times, and season-to-season repeatability. This means less hardware, faster times recovering from a shading event, and the confidence that your guidance lines and boundaries won't shift from year to year.

The StarFire™ 7000 Receiver offers a new correction level with accuracy like RTK Radio. The SF-RTK correction level provides 2.5-cm (1-in.) horizontal accuracy without the need for additional hardware. This is an improvement of 17 percent from the previous generation of StarFire receiver. The SF-RTK signal uses two additional satellite constellations (BeiDou and Galileo) as well as both GPS (United States) and GLONASS (Russia) satellites.

The StarFire 7000 and StarFire 7000 Integrated Receivers simultaneously track correction signals from up to three StarFire correction satellites. The receiver tracks and uses correction signals from all StarFire satellites in view and intelligently chooses one that delivers the best performance. When the receiver moves into an area where the primary StarFire signal is blocked, such as near a tree line, the receiver automatically switches to an alternate StarFire signal (if visible) to help maintain accuracy and performance.

NOTE: Compare this to the previous StarFire 3000 Receiver that was only capable of tracking one StarFire signal at a time and could wait up to 4 minutes to initiate the switch to the next available signal.

Repeatability defines how accurately the receiver calculates its position over a relatively long-term window.

NOTE: SF-RTK uses satellite corrections only and does not require the use of an RTK Radio. RTK Radio may still be required in the following scenarios:

• iGrade™ water management
• Areas with thick tree lines or obstacles that could cause shading of the receiver
• Long-term repeatability beyond 5 years
• Hilly terrain

Many factors contribute to the time it takes to achieve desired accuracy from the StarFire™ receiver. Global Navigation Satellite System (GNSS) signal quality can be a contributor, especially when multipath errors occur. Multipath errors occur when satellite signals reflect off nearby surfaces. When the receiver antenna captures a multipath signal, it takes time for the receiver to filter out actual GNSS signal directly from the satellite versus reflected signal from a nearby object. This contributes to the time it takes to achieve desired accuracy.

 

The StarFire 7000 and StarFire 7000 Integrated Receiver use an integrated terrain compensation module (TCM) to adjust the calculated machine position based on the terrain on which it is operating. The TCM adjusts for roll, pitch, and yaw motion to improve receiver and AutoTrac™ system performance when operating in challenging conditions such as hilly ground.

• TCM ensures accurate Section Control and AutoTrac guidance performance.
• TCM provides input data such as pitch to systems like the ActiveYield™ monitoring system on combines.
• The StarFire 7000 Integrated Receiver uses software to project into the position as the StarFire 7000 Receiver to ensure same performance and accuracy.
• The StarFire 7000 Integrated Receiver comes factory calibrated, ensuring the highest possible performance and precision.

ADVANCED TCM CALIBRATION

As accuracy and repeatability continue to be more important to get to plant-by-plant accuracy, the systems in place today must evolve to enable this capability. Like the StarFire 6000, the StarFire 7000 offers an Advanced TCM Calibration feature.

 Benefits:

• Removes the guesswork out of positioning a machine and implement in the exact same spot when turning around.
• Removes the need for a level surface.
• Adds higher precision to the TCM calibration by gathering and comparing multiple points.
• Calibrates both the machine and implement receiver TCM at the same time.

How it works:

• Roughly 100.6 m (330 ft) of space is required for the calibration.
• During the calibration, speed should not exceed 6.4 km/h (4 mph).
• If an error occurs during the calibration, the operator is notified.

• Select Advanced TCM Calibration from the device list in the display.
• Follow the on-screen prompts to set up a guidance line.
• Drive the guidance line using AutoTrac automated steering from point A to point B.
• Manually turn and resume AutoTrac steering, driving the guidance line back to point A.

This completes the calibration.

Compatibility:

• StarFire 7000 Receiver or StarFire 7000 Integrated Receiver
• StarFire 6000 Receiver or StarFire 6000 Integrated Receiver with software update 20-2 or later
• Gen 4 4600 CommandCenter™ Display with software update 20-3 or later
• Gen 4 4640 Universal Display with software update 20-3 or later
• Must have an AutoTrac activation

With Ethernet connectivity on the StarFire 7000 Integrated Receiver, you can save up to 60 minutes per year while performing over-the-air software updates to keep your technology in sync with the latest features.


Improved RTK

• Better accuracy and more reliable RTK
• Fast startup and shading recovery times, less line jumps, and more reliable performance under shading environments
• Better RTK-X performance compared to StarFire 6000 or StarFire 3000 Receiver base
• Vertical accuracy improvement

NOTE: Data collected when running a StarFire 7000 Receiver base with a StarFire 7000 rover.

NOTE: RTK Radio still requires the use of a compatible radio.



Drop-in replacement and serviceability

As John Deere continues to advance their technology (like the StarFire™ 6000 Integrated Receiver), the StarFire 7000 Integrated and StarFire 7000 Receivers are designed with modular components, making the unit a drop-in replacement for the previous generation of integrated receiver. You never have to worry about having outdated hardware.
