use Illuminate\Database\Eloquent\Model;

class Conexoes extends Model
{
    //
    protected $connection = 'gps';
}

Controller

namespace App\Http\Controllers\Rastreamento;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Conexoes\Positions;
use App\Rastreamento\Markers;

class PosiceosController extends Controller
{
  private $positions;

  public function index(){
    $this->setConnection('banco2');
