Positional Qualityとは?

• Positional Quality は、カタパルトに固有の位置品質パラメーターで表されるGPSデバイスとグローバルナビゲーション衛星システム（GNSS）間の相対信号強度です。 Positional Quality はコンソールとクラウドの両方で調査できます

Positional Quality設定する方法

• Positional Quality モジュールがオープンフィールドアカウントに適用されている必要があります。 モジュールを追加する場合は、 サポートにお問い合わせください 。モジュールがアカウントに追加されたらオープンフィールドコンソールからFastsyncをしてコンソールで位置品質パラメーターを表示してください。 

Viewing Positional Quality Metrics in the OpenField Console

Graphing Positional Quality

1. In the OpenField Console, open the desired Activity. 
2. Right click the desired Athlete from the Active Players Group and select Graph to graph the athletes.
   
   
3. Right click on the Athlete's name at the end of the graph trace. See Graphing Data for more information.
4. Select 'Graph Post Parameters'.
5. Select Positioning Quality.
   
   
6. The Positional Quality will be graphed throughout the Activity
   
   

Exporting Positional Quality from a CSV

1. In the OpenField Console, open the desired Activity. 
2. Right click the desired Athlete from the Active Players Group and select Export Sensor CSV.
   
   
3. Open the downloaded CSV. Positional data is collected every 0.1 second (10Hz) for the Activity and recorded in the Positional Quality (%), HDOP and #Sats columns of the CSV export. 

Viewing Positional Quality Metrics on OpenField Cloud

1. From the OpenField Cloud, navigate to a Dashboard and create a new Widget for the Positional Quality. See Cloud Widgets for more information on creating Widgets.
   

2. Select 'Render as = Table' and proceed to the Parameters Tab.

   
   

3. Scroll through the Parameter Categories until you find "Positional Quality". From this drop down, add or remove parameters to configure the parameters visible in your table. 

   See Positional Quality Parameter Definitions for definitions of each of the Parameters.
   
   
   
   
4. When finished configuring your Widget, select Done.
5. Open an Activity to view the Positional Quality data.
   
   

Positional Quality Parameter Definitions

GNSS Quality

The relative signal strength between the GPS Devices and the Global Navigation Satellite System (GNSS) for the selected Period/Activity(s) expressed as a percentage, with 100% being strongest GPS lock possible

Average GNSS Quality

The average relative signal strength between the GPS Devices and the Global Navigation Satellite System (GNSS) for the selected Period/Activity(s) expressed as a percentage, with 100% being strongest GPS lock possible

Minimum/Maximum GNSS Quality

The minimum/maximum relative signal strength between the GPS Devices and the Global Navigation Satellite System (GNSS) for the selected Period/Activity(s) expressed as a percentage, with 100% being strongest GPS lock possible

HDOP

The dilution of precision which measures how much the geometrical arrangement of the satellites being measured will affect the precision of the result

Average HDOP

The average dilution of precision which measures how much the geometrical arrangement of the satellites being measured will affect the precision of the result

Minimum/Maximum HDOP

The maximum/minimum dilution of precision which measures how much the geometrical arrangement of the satellites being measured will affect the precision of the result

Satellite Count

The number of fixed satellites per data point

Average Satellite Count

The average number of fixed satellites per each data point (10Hz) for a selected Period/Activity(s)

Minimum/Maximum Satellite Count

The minimum/maximum number of fixed satellites per each data point (10Hz) for a Period/Activity(s)
