ArcGIS Collector と外部 GPS

バージョン 10.4 のリリースにより、iOS の Collector で空間 GPS 精度を確認できるようになりました。GPS の品質向上を試みるために、いくつかの外部 GPS ユニットをデバイスに接続してみました。Bluetooth 経由で外部デバイスを接続し、その後 Collector を設定してデバイスを認識させると、アプリ内で GPS を使用する機能がすべて停止します。（精度ウィンドウが消え、地図の GPS トグルボタンが無効になります）外部 GPS ユニットの接続を解除すると、GPS 機能は復活します。これに遭遇した方はいらっしゃいますか？解決方法について何か提案はありますか？Trimble のユニットで成功した方はいらっしゃいますか？<\/P>

Follow up on this topic for anyone interested. Pairing certain low accuracy external gps devices (tested the Garmin Glo) can be done simply by connecting via bluetooth without configuring the connection in Collector. We then attempted to connect a Trimble Pro6H with NMEA and Floodlight activated. We had to purchase the AMAN enterprises NMEA-BT unit to send the gps stream to Collector. You then have to download an app called NMEA Talker and configure it. After that go through the Collector settings menu to change the provider and configure your Location Profile. This worked very well for us. We tied into a local RTK subscription service and were able to see better than submeter quality data. Two downsides, one is that Collector does not seem to like to report better than 12.3' of horizontal accuracy. We have to perform more testing to quantify this. Second was with the Pro6H unit itself. We found out that upon powering the Trimble unit down, the NMEA output is toggled off. So if an end user planned to use it for the day, they would have to connect the Trimble unit to their desktop and enable the NMEA string again. This is an inconvenience for now, but limits our end users to qualified GPS/GIS field crew members.
