下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了更好的理解本申请实施例公开的一种定位验证方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1a，图1a为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1a所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备和两个或两个以上的终端设备。图1a所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(Long Term Evolution，LTE)系统、第五代移动通信系统、5G新空口系统，或者其他未来的新型移动通信系统等。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101和可以为演进型基站(Evolved NodeB，eNB)、传输点(Transmission Reception Point，TRP)、NR系统中的下一代基站(Next Generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(Central Unit，CU)与分布式单元(Distributed Unit，DU)组成的，其中，CU也可以称为控制单元(Control Unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(Mobile Station，MS)、移动终端设备(Mobile Terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(Mobile Phone)、物联网(Internet of Things，IoT)终端、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(Industrial Control)中的无线终端设备、无人驾驶(Self-Driving)中的无线终端设备、远程手术(Remote Medical Surgery)中的无线终端设备、智能电网(Smart Grid)中的无线终端设备、运输安全(Transportation Safety)中的无线终端设备、智慧城市(Smart City)中的无线终端设备、智慧家庭(Smart Home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
随着无线通信技术的不断发展，卫星通信被认为是未来无线通信技术发展的一个重要方面。在NTN应用(比如卫星通信)的场景下，由于发送端与接收端存在较长的信号传输距离，导致数据传输有较大 的时延。对于存在有上下行关系的传输，目前的标准化讨论中确定了引入偏移量Koffset的参数来补偿传输时延。如图1b和图1c所示，图1b为网络设备侧上下行定时对齐传输方式示意图，图1c为网络设备侧上下行定时不对齐传输方式示意图。
终端设备可以通过星历信息和公共定时提前(common timing advance，common TA)的相关信息来补偿传输时延。星历信息和common TA的信息是通过系统信息通知给终端设备的。终端设备需要获取自身的位置信息，以便于进行上行同步的补偿。
相关技术中，终端设备可以基于GNSS测量获取自身的位置信息，并上报给网络设备，然而对于网络侧来说，该位置信息可能是虚假的或者可能被篡改，是不可靠的。
在某些部署场景下，终端设备102可以观测到多个卫星，因此可以考虑通过多个卫星来获取位置信息，通过网络设备确定的位置信息，可以用来验证终端设备基于GNSS测量上报的位置信息是否可靠。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的定位验证方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种定位验证方法的流程示意图。需要说明的是，本申请实施例的定位验证方法由终端设备执行。该方法可以独立执行，也可以结合本申请任意一个其他实施例一起被执行。如图2所示，该方法可以包括如下步骤：

在本申请实施例中，终端设备向网络设备发送基于GNSS测量的位置结果，可以周期性发送该位置结果，也可以在网络设备的触发下发送该位置结果。
在一些实施方式中，终端设备能够接收网络设备发送的第一配置信息，并根据该第一配置信息的配置，周期性向网络设备发送基于第一定位测量得到的第一位置信息。该第一配置信息用于终端设备发送第一位置信息。
可选地，该第一配置信息中可以包括用于确定发送第一位置信息的周期信息，以及终端设备发送该第一位置信息等相关的配置，比如发送第一位置信息的时频域位置、包括该第一位置信息的信令或者信息等等。

其中，发送该第一位置信息的配置是终端设备发送该第一位置信息相关的配置，比如发送第一位置信息的时频域位置、包括该第一位置信息的信令或者信息等等。
也就是，作为一种可能的实现方式，该第一指示信息用于指示终端设备是否发送该第一位置信息，终端设备能够根据网路设备发送的第一指示信息的指示，确定是否向该网络设备发送第一位置信息。
作为另一种可能的实现方式，该第一指示信息用于指示发送该第一位置信息的配置，终端设备能够根据网络设备发送的该第一指示信息的指示，根据第一指示信息指示的配置向网络设备发送第一位置信息。
作为又一种可能的实现方式，该第一指示信息用于指示终端设备是否发送该第一位置信息，以及发送该第一位置信息的配置。
步骤202，接收该网络设备发送的第二定位测量配置。
在本申请实施例中，终端设备能够接收网络设备发送的第二定位测量配置，并根据该第二定位测量配置，执行第二定位测量。
可选地，在本申请各实施例中，该第二定位测量可以为多卫星辅助的定位测量。
在本申请实施例中，该第二定位测量配置包括以下至少一种信息：
一个辅助定位的卫星的标识；
