StarFire™ 7000 Receiver

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 with SF3. 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 in countries we cannot guarantee SF-RTK repeatability (see list under SF-RTK repeatability)
• Land leveling

John Deere’s latest satellite correction offering provides customers with simplified access to Radio RTK like accuracy and repeatability. Prior to SF-RTK, customers had to purchase additional hardware, RTK Ready or Permanent Licenses, and in most use cases work with a local John Deere dealer to access their base station network to use Radio RTK.

SF-RTK eliminates that complexity through offering the same level of accuracy and repeatability from the sky! Plus, with SF-RTK there’s no need to switch base stations when moving between fields like seen with Radio RTK.

What does SF-RTK do?

The StarFire 7000 utilizes four GNSS satellite constellations, which are corrected through John Deere’s StarFire network to provide sub-inch horizontal accuracy. This provides customer’s our highest accuracy level, along with long-term repeatability (where applicable) to enable advanced guidance features and the confidence that guidance lines and boundaries won't shift from year to year.

Why should customers use SF-RTK?

Customers are continually looking for simplified solutions that deliver the value needed for their operation. SF-RTK offers a lower cost of entry for customers compared to Radio RTK, making this solution an easy decision for customers looking to use a high precision correction signal. Why pay for additional hardware, permanent licenses and base station access fees when SF-RTK only requires a yearly license to operate on your StarFire 7000 or StarFire 7500 receiver.

2. SF-RTK 1-year license

Choosing the right correction mode

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.

Choke plate

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.

Advanced TCM Calibration page in the display

• 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

Serviceability

The StarFire 7000 Universal Receiver has more than 20 parts that are completely serviceable. In the unlikely event that there is a problem with the system, many of the individual components can be replaced without replacing everything. This saves you time and money that can be used in other areas of your operation.

Shared signal enables the pairing of two StarFire receivers and allows  communication between them to improve relative system accuracy when utilizing Machine Sync, AutoTrac™ Implement Guidance (ATIG), Active Implement Guidance™ (AIG),  or AutoPath™ advanced precision ag technologies.

Supported configurations:

The following receivers are compatible with shared signal and can be used interchangeably.

• StarFire™ 7500 Receivers
• StarFire 7000 Receivers
• StarFire 6000 Receivers
• StarFire 3000 Receivers

NOTES:

• StarFire 3000 Receivers are no longer a supported configuration with Machine Sync. As part of our ongoing commitment to enhancing our products, we are discounting support for Gen4/G5 Machine Sync with StarFire 3000 receiver, starting in May of 2024. See DTAC solution 224346 for more information.
• When using shared signal, the system matches the correction signal from the leader, so the leader must have the higher correction The follower may have a lower correction signal, but the overall system accuracy will reflect that of the leader. This is applicable for AutoPath and ATIG operations as well.

Leader Examples: Combine or pull-type harvester in a Machine Sync operation

Follower Examples: Grain cart tractor in a Machine Sync operation

The leader and follower  must be on the same software version. There are no configuration limitations on leader/follower setup between receiver models as long as they are a supported Machine Sync model.
