starfire™ 7000 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.

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 choke plate hardware in the StarFire™ 7000 Receiver more accurately directs GNSS signals into the antenna. With the addition of this choke plate, there is a 66 percent reduction in the time it takes to acquire an SF-RTK correction signal from previous generations of StarFire™ receivers. This means you have more time to be productive and get the job done quicker.

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.

With the StarFire™ 7000 Receiver and SF-RTK correction level, you can have confidence from year to year that your guidance lines and boundaries will stay where they need to be. The StarFire™ 7000 Receiver has up to 5 years of repeatability guaranteed. This is an 85 percent increase from previous generations of StarFire™ receivers.

StarFire™ 7000 and StarFire™ 7000 Integrated repeatability:

SF1: no repeatability, position drifts over time

SF-RTK: +/- 2.5-cm (1.2-in.) season-to-season repeatability (where applicable)

SF-RTK repeatability specifications have been validated through at least a 5-year period. SF-RTK repeatability claims are only valid after the receiver has completed a full pull-in and is operating at 100 percent accuracy.

RTK Radio: +/- 2.5-cm (1-in.) long-term repeatability

RTK Radio repeatability specifications are based on a properly installed RTK base station and a base station position that has not been modified after initial setup.

NOTE: Repeatability may be impacted by large unpredictable geological events such as earthquakes.

VALUE OF REPEATABILITY

Repeatability defines how accurately the receiver calculates its position over a relatively long timeframe. Repeatability is measured at the receiver and does not take into account additional error sources such as AutoTrac control system error, ground conditions, or implement drift.

In-season repeatability is critical when using AutoTrac™ for multiple jobs throughout the growing season, such as creating AutoTrac guidance lines during planting, then using those same guidance lines to complete subsequent jobs like side dressing fertilizer, post-emerge spraying, and harvesting.

Long-term repeatability is critical when mapping interior and exterior boundaries for later use as input to John Deere Section Control on planters, sprayers, and fertilizer applicators. It is also critical for growers that use the same AutoTrac guidance lines over multiple seasons for operations like subsurface-drip irrigation, controlled traffic, or alternating planter spacing between the rows from a previous season.
