app端使用uni.getLocation定时获取经纬度，经常会出现定位不准确，绘制的轨迹偏移很大，这应该怎么解决呢？

定位

<map id="map" style="width: 100%; height: 300px;margin: 10rpx 0;" :latitude="latitude"  :longitude="longitude" :markers="covers" :polyline='polyline' />  

setInterval(() => {     
        uni.getLocation({    
          type: "gcj02",    
          isHighAccuracy: true,    
          success: (res) => {    
            let longitude = res.longitude;    
            let latitude = res.latitude;    
            //polyline    
            this.polyline[0].points.push({ longitude, latitude });    
            //center    
            this.longitude = longitude;    
            this.latitude = latitude;    
            //marker    
            this.covers[0].longitude = longitude;    
            this.covers[0].latitude = latitude;    

            this.polyline = [...this.polyline];    
            this.covers = [...this.covers];    
          },    
          fail: (res) => {}    
        });    
      }, 10000);
