Compared with the previous generation “P-1 GPS”, “P-1 Mark II GNSS” supports Beidou, GLONASS and QZSS. Totally 89 satellites which can ensure rapid and effective positioning at any location in the world. And improving positioning accuracy and reliability.
How much has the performance improved?
1. What is the positioning accuracy of the P-1 Mark II?
It refers to the high-precision positioning performance that P-1 Mark II can provide: Horizontal direction 1.5m/CEP(50%); 4.0m/CEP(95%).
CEP refers to Circular Error Probable. 1.5m/CEP(50%)* means that the probability of the track points falling within a 1.5m radius is greater than 50%; 4.0m/CEP(95%)* means that the probability of the track points falling within a 4.0m radius is greater than 95%.
*Data from testing in ideal open environments
2. Static drift test
Test purpose: To evaluate the static drift suppression performance of the receiver (P-1 Mark II config file parameter: Speedmask=OFF).
Test duration: 8 hours
Test time: UTC 2022-04-25 18:00:00 ~ 2022-04-26 01:59:59 | Average speed: 0.0km/h
Location: On the roof of the building, P-1 Mark II is placed face up, and the GNSS status lamp is blue.
Surroundings: In a 50m radius, there are no objects higher than above-mentioned location.
Remark: The P-1 Mark II CEP(50%) 0.89m accuracy is the static drift test result. When combining the static and dynamic test, the overall accuracy is CEP(50%) 1.5m.
3. Low-speed driving track test
Test purpose: Record three consecutive times along the same route to evaluate the smoothness of the low-speed driving track.
Test time: UTC 2022-07-12 18:04:20 ~ 18:11:48 | Average speed: 6.5 km/h
Location: Under the front windshield of the vehicle, P-1 Mark II is placed face up, and the GNSS status lamp is blue.
Surroundings: Houses and trees are densely distributed nearby.
Dual mode USB interface:
The USB port of P-1 Mark II supports two operating modes: USB disk mode and GNSS receiver mode, which can be automatically switched according to the usage scene.
Multi-platform compatible with Windows, macOS, Android and Linux.
- USB disk mode. Read files from the MicroSD card in P-1 Mark II.
- GNSS receiver mode. P-1 Mark II can be used as an external GNSS receiver, and users can view the real-time location data.
1. IP66 all weather
P-1 Mark II can function well under all weather conditions at ease, including the icy, frosty, rainy and snowy days as well as deserts, Gobi, and the high-humidity environment!
P-1 Mark II boasts an IP66 protection rating, and can be used in all weather conditions.
All connections between the buttons and the case, as well as the rubber cover at the bottom, are sealed to shield P-1 Mark II from water and dust in any extreme weather.
P-1 Mark II also works in an extended range of temperature from -10°C to 50°C, to ensure normal use at high latitudes and in tropical areas.
2. Reliable and stable data storage
Data storage stability is critical, and we have improved the reliability of P-1 Mark II.
We have optimized the hardware design to ensure that it faithfully records every track point during work. The reliability of data is better than 99.998%* under long-term and large-scale recording.
The Columbus data logger series has provided stable and efficient logging at a very low failure rate since its launch in 2009. So far, Columbus has supplied high-quality products to hundreds of enterprises and institutions around the world.
* Based on our test results. Track points are lost at a probability of less than 0.002%, or no more than one track point is lost in every 50,000 records.
Easy to read and process
Storage performance is vital to ensuring its stable logging and dependable storage over a long term.
P-1 Mark II uses the MicroSD card storage and supports massive-capacity SDXC cards.
The storage is readily accessible through any plug-and-play USB port, providing seamless compatibility with Windows, Mac OS, Linux and Android, that enables you to quickly read tracks across these platforms.
To facilitate statistics and management of massive volume of data collected in a long time period, P-1 Mark II Pro neatly arranges its logs by automatically naming track files after date and time, and folders by year and month.
CSV, GPX and NMEA
P-1 Mark II offers three original track formats for selection: CSV, GPX and NMEA, which is convenient for secondary development and application.
You can also use the desktop software "Time Album Pro" to view the tracks and conversion.
"TimeAlbum™ Pro" is equipped with the most advanced track editing function and personalized settings with the ability to provide the latest and multiple maps, such as Google and Openstreetmap.
"TimeAlbum™ Pro" can assist in your background work, and can efficiently convert, manage and plan the tracks.
It is compatible with Windows, Linux and Mac OS.
1. Long battery life
The battery life of P-1 Mark II is more than 48 hours*, enough for a whole week's work (8 hours a day, 5 days a week) .
* Continuous recording at 1Hz, with the ambient temperature at 20°C.
2. Motion Detection Mode
Columbus invented the Motion Detection Mode on the V-990 in 2011 and is widely welcomed by users.
The ordinary data logger still works after suspended movement or positioning failure, which consumes power and generates redundant track points. When P-1 Mark II is in a static status or has lost the satellite signal for over 5 minutes, it is automatically on standby to save energy.
The Motion Detection Mode extends battery life and optimizes data. Short press the power button to turn on or off the mode.
3. On-board Auto on/off
P-1 Mark II Pro is automatically powered on/off with the vehicle, no need for manual operation.
*This function needs to be turned on in the configuration file.
4. Spy Tracking Mode
Columbus invented the Spy Tracking Mode for ultra-long battery life.
This mode achieves ultra-long battery life (up to 24 days) by interval work, and is suitable for tracking vehicles or people when charging is not convenient.In this mode, P-1 Mark II gets positioned and logs 8 track points at a certain time interval.
In actual use, the spy tracking mode can not only extend the battery life but also optimize the track data.
1. Personalized configuration
P-1 Mark II is a professional data logger that can be customized. You can configure the following parameters at any time according to the needs of the project.
2. Firmware customizable and self-updated
We are constantly improving P-1 Mark II. You can download the latest version of the firmware on the official website and update it by yourself to ensure that the device is in the best condition. The update is user-friendly.
In addition, you can also tell us special requirements by email (firstname.lastname@example.org), and we can customize the special version of the firmware accordingly.
