# GnssMultiFrame
<a name="API_GnssMultiFrame"></a>

Global navigation satellite system (GNSS) multi-frame object used for positioning. Contains multiple GNSS scan captures that are combined by the solver.

<a name="API_GnssMultiFrame_Contents"></a>

 ** Captures **   <a name="iotwireless-Type-GnssMultiFrame-Captures"></a>
List of GNSS scan captures. Each capture contains a payload from a single GNSS scan. The number of captures must be 2, 4, 8, 16, or 32.  
Type: Array of [GnssCapture](API_GnssCapture.md) objects  
Array Members: Minimum number of 2 items. Maximum number of 32 items.  
Required: Yes

 ** AssistAltitude **   <a name="iotwireless-Type-GnssMultiFrame-AssistAltitude"></a>
Optional assistance altitude, which is the altitude of the device at capture time, specified in meters above the WGS84 reference ellipsoid. This parameter is required when Use2DSolver is enabled.  
Type: Float  
Required: No

 ** AssistPosition **   <a name="iotwireless-Type-GnssMultiFrame-AssistPosition"></a>
Optional assistance position information, specified using latitude and longitude values in degrees. The coordinates are inside the WGS84 reference frame.  
Type: Array of floats  
Array Members: Fixed number of 2 items.  
Required: No

 ** CaptureTimeAccuracy **   <a name="iotwireless-Type-GnssMultiFrame-CaptureTimeAccuracy"></a>
Optional value that gives the capture time estimate accuracy, in seconds. If capture time accuracy is not specified, default value of 300 is used.  
Type: Float  
Required: No

 ** Use2DSolver **   <a name="iotwireless-Type-GnssMultiFrame-Use2DSolver"></a>
Optional parameter that forces 2D solve, which modifies the positioning algorithm to a 2D solution problem. When this parameter is specified, the assistance altitude should have an accuracy of at least 10 meters.  
Type: Boolean  
Required: No
