topcon vs trimble

Макс, в R8 уже тоже есть оба типа модемов

 

max7, этих R8 три версии, так что ты когда пишешь говори о какой, а вообще я бы не взял не GR-5 не Trimble R8.
Я бы взял вот это

1. Number of channels and tracked signals vary according to receiver configurations.
2. RMS Values. Accuracy depends on the number of satellites used, obstructions, satellite geometry (DOP), occupation time, multipath effects, atmospheric conditions, baseline length, survey procedures and data quality.
3. 10 Hz standard. Higher rates available as options.

 

kircozz, с чего? у меня на прежнем месте остались 3 шт Sokkia GRX-1 на 72 канала (Он же Hiper II) я восторге, а тут то же корпус, а плата от GR-5. Зато никаких проблем с акками при использовании последних линеек тахеометров Topcon/Sokkia, они там одинаковые.

 

kircozz, max7, в отличии от GR-3/5 я не парился есть там антенна или нет. И как у Valang там крышку приемника не сломать, не гибкая часть вместе с разъемом защищена в углублении.

Вы же новый тах купили? вот там в приемниках такой же акк и аналог его стоит сущие копейки, а главное количество зарядных устройств уменьшается

 

А к нему вот такой контроллер
