Getting ready: preparing your tools and systems for the new season
In preparing for the new field season, it is essential to begin with safety. Users should always be mindful of the work environment and the risks users may be exposed to. Safety briefings, signage, and communication are all helpful in having a safe environment for users and equipment.
Once users have established a safe environment, consider the needs of the project by asking these three questions:
1. Do we clearly define the project goals and deliverables?
2. Do we have the tools, team, and training to accomplish the job?
3. Do we have a written plan of execution?
After addressing these three questions, assessing the gear is the next step. Users should ensure that the equipment being used will meet the need of the project. It can be helpful to define who, what, and how the gear will be used to have a successful workflow. Planning this out can benefit users in the field data collection process.
A users system for field data collection may include, but is not limited to:
- Field Computer
- Tablet
- Smartphone
- Sensor
- GNSS Receiver
- Software
- Reference Data
- Workflows
- User Interface
- Storage
- Other Sensors/Instruments
- Soil Sampler
- Water Probes
- Tree Core Tool
- Animal ID Tags
- Camera
- Tape Measure
Ensuring your equipment meets your needs
Key questions to ask before purchasing a field computing device may include:

GPS receiver set-up and options for optimal performance in various conditions
To get the highest level of accuracy from a GNSS receiver, users should choose the best correction service to meet the needs of the job. This can depend on the type of GNSS receiver being used, the budget, and where the job is in the world. Some of the most common correction services are satellite-Based Augmentation Systems, or SBAS, Network Transportation of RTCM data via Internet Protocol or NTRIP, and Atlas.
Benefits of SBAS:
- Provides correction to GPS data, reducing ionospheric error
- The biggest source of GNSS error
- Reduces 3-5m positioning to sub-meter
- Free, no subscription necessary
- Can tolerate signal interruption
Challenges of SBAS:
- Geosynchronous Satellites
- Can be blocked by terrain
- Limited Coverage Areas
- Regional service
- Ionospheric correction only
Benefits of NTRIP:
- High real-time accuracy
- Fast solutions, < 1 minute
- Local correction service
- Available in most populated areas
Challenges of NTRIP:
- Limited Coverage Areas
- Regional service
- Requires continuous cellular data connection
- Operational Costs Vary
- Datum and Projections can vary
Benefits of Atlas:
- Worldwide Coverage
- Multiple Accuracy Levels
- Selectable subscription lengths (H30 & H10)
- Can tolerate interruptions once convergence is achieved
Challenges of Atlas:
- Geosynchronous, can be blocked by terrain
- Longer convergence times
- Basic – 5 minutes
- H30 – 10-15 minutes
- H10 – 30 minutes
- Subscription-based
Best practices for accurate and reliable data capture
For accuracy and reliable data collection in the field, users should consider the following questions:
- How will the device be carried?
- What is the intended use of the device?
- Does the job require maximum precision?
- Will the project require a large area to be covered?
- Does the job need users to carry additional equipment?
Users should consider mounting the system on a pole to get maximum precision in the field.
Users might consider using a backpack mount to cover a large area in an efficient amount of time.

Improving the accuracy of data to be collected and mapped can be a challenge without applying best practices. Best practices for better GPS accuracy in the field can be accomplished by following these steps:
- Get a good GPS Ephemeris and Almanac on the receiver being used.
- Set a good antenna mask angle.
- Be aware of obstructions in the area.
- Get supportive tools and equipment.
- Use applications that can interact between the GNSS Receiver and the device.
- Check the settings of the device.
Bringing it all together for a successful project
It takes all hands on deck to prepare for a successful project. Users must come prepared with the appropriate equipment and software. The team must be properly trained to use the software and hardware to be effective and efficient in the field. Everyone should know the project needs, how to troubleshoot common problems, and know the passwords and logins to ensure that data can be collected and stored properly. These considerations can make all the difference in the start and completion of fieldwork mapping and data collection. To learn more about what Juniper Systems has to offer, contact our team today.
